thx gem and kitt, doing exactly as you guys have posted. my teeth are fairly bad, a combination of grinding, meds, anti-psychotics and years of smoking. had a massive migraine this morning, with a lot of acid coming up. feel a tad better, only 1 tooth throbbing at the moment. will apply for course on-line!!! thx to my mates, bob and irene for looking after me. oh, t1 diabetes hasn't helped, albeit sugars are impreoved, as are the water works. thx 4 your posts guys, luv, jamie.
