I've been on it for about 2 years. I started out at 16mg/day, but I'm down to about 6/day now. I had to start wearing upper dentures while I was on the sub and I had so much trouble with them that I finally realized it was because of the med drying my mouth out so much. I've got implants now and dentures with no palate, but they still bother me so I HAVE to go completely off the sub. And before anyone mentions it; the dentures were not the result of medication or not maintaining my teeth. I had a REALLY bad, stupid dentist. But, you can't undo pulled teeth, so I have to deal. Any help, advice, guidance or prayers I would greatly appreciate.
