I know 100 mg isn't supposed to be enough, but before I finally saw an LLMD , my PCP humoured me even though he didn't think I had lyme, so he gave me that prescription for one month. I think it was just once a day but could have been twice a day. That was a long time ago.
I did get better, but relapsed in a couple of months so the same prescription for 6 months. This time I stayed well for several months.
After that, I just felt tired and achy and forgetful until I saw LLMD. PCP said I couldn't have lyme anymore.
I've always wondered why it worked. He'd probably say it was placebo affect--but I doubt it.
Also kind of reached a plateau after on doxy, ceftin, flagyl, etc for 18 months with LLMD.
