wow. didn't know there was anyone else who needs to use grindcare longer term, like me.
there are only 3 situations in which I ever got CES biofeedback start kicking off constantly thus problematically. But for me, I always realized eventually that it was my user error:
1. if I slapped on a gel pad, and didn't notice that when I tore off and trashed one the day before, and I had left a gel dot somewhere on the pad, so now 2 leads get a connection to each other when I slap a new sticky pad right over the old gel dot. This one is easy, because you notice right away during or immediately after nightly calibration, so once you realize what you did, you just rip off the any leftover gel dots and the pad, and now make sure that you lay a single sticky pad on a clean lead pad, right side up. Definitely user error.
2. More than once, I've gotten CES biofeedback start kicking off, immediately after I do the nightly calibration, feeling it almost continuously, as soon as sleep mode begins. Inevitably, I realize that I must have zoned out during nightly calibration, and sat there with my mouth hanging open, staring off into space dumbly, when I was supposed to be clenching to calibrate. Again, since you notice this right away, it's easy to fix. So, I've been assuming that the only mistakes I can make with a repetitive task are dumb ones, like these. I wonder if the new automatic mode feature is for people who zone out like me sometimes.
3. Way back with my first lead pad, I yanked it by the wire (before they changed their manufacturing to make this hard to do), until I actually loosened the connection where the wire and the pad connect. And it was unusual for a bad connection, because it didn't just die completely, after I yanked it one night. It took a while, acting flakey, reading nothing some nights, and the gaping of the pad separating top from bottom was visibly obvious, where the wire connects. But I have never experienced this problem with with any of the current leads. They made that area really strong in manufacturing, long before they rolled out to the USA.
So, I wonder what the heck you are doing to get constant CES biofeedback, that starts later on in the night? If your model lets you set sensitivity seperately in the configuration menu (with the wrench icon), I would keep the sensitivity low, but I think the newer models don't bother with a seperate, "set sensitivity" in config., since I bet calibration makes this redundant.
And if you have been careful to clench (not grind and move) during configuration, using at least 60% of your clenching force, I don't see how you could have biofeedback start kicking off continually sometime later in the night. If you forget to clench without grinding around, you could indeed confuse your calibration, and if you used a move while calibrating, that you don't do again after calibration until later, during deep sleep, it could come back to bite you then, maybe? A grinder (as opposed to a clencher like me) might not notice that the calibration instructions say clench, don't grind moving your teeth around, during calibration.
Otherwise, you have me stumped. The only thing that I can think of is to wonder what it means when you say you taped it with the result that you managed to get too many biofeedbacks during sleep. Is it somehow possible to get some kind of bad connection like my case number one, by taping in such a way that you lose your flat connection to your skin? Could a long piece of tape starting before the pad on your skin, along the pad, and after the pad onto your skin, done on a curve of your head, or curling the outer leads up and away from your skin by being really tight...could this make a connection between two of the 3 leads? I can't quite imagine it, but it is interesting that you say you were able to get constant firing, depending on how you tape over the pad.
I do remember that when my sleep was very disturbed by bruxing, before Grindcare calmed it down, I would yank or even pull it off sometimes. But, since the biofeedback level number that I choose is never strong, the CES biofeedback never disturbed my sleep. But others, who don't have my sensory nerve damage, probably can set the level of CES biofeedback overly high, to interrupt more than just bruxing. So, finding a biofeedack level during calibration that is only high enough to interrupt your bruxing, and no higher, seems like something worth concentrating on. But even in this case, it should bother you only if both your level's too high AND your connection is bad (and the connection bad in a way I would have thought difficult to get with any regularity). Or if your level is too high and your calibration includes movements. So, I'm really grasping for ideas here, telling you to doublecheck that you use, for example, level 4 versus 9, if 4 is enough to get your bruxing trending down. And if you use tape, use a short piece on one end, and another on the other, and make sure it is on a flat area of your temple over the temporalis?
Of course, if you can reproduce this problem at will, you can figure out what you are doing to receive this problem, but that's sometimes easier said than done. I agree with you that it would be very annoying, when you are seeking restorative sleep. Good luck debugging it, and if you learn anything, please share.
btw, as far as getting a forum supported by the Grindcare developers themselves, I expect that wouldn't be efficient - most people aren't going to debug as patiently as you or I, and will need to have live support, I bet. Hence the prescription requirement in the USA. And like I said to FSDUAL, I think that the people in Denmark are engineers, supporting many countries's languages, so if we want a forum, it would have to be supported by users, or maybe when there is a big enough distributor here. I noticed that some Grindcare distributor in the UK seems all over the net, with a name of a multi-site dentistry group, called something like "Smiles" or somesuch, but even they don't have a forum. When we have big distributors here, maybe someone will have enough uni-lingual users to support by forum efficiently. But until and unless, I bet users will start forums like they did for apnea, and one or two with have enough super users, so that they end up being useful, generally. That's how that user support forum at Mass General grew, called braintalk, grew (it was started by the guy who later started second life). They have some users that are more knowledgeable than many doctors, but I think it leans toward neurological problems. Well, enough rambling for today. Good luck.
