((((((((Dec)))))))))))) Sounds like some "fun" symptoms...

I'm on 187.5mg at the moment... I did start on 75mg though...

I feel really bad if I forget a dose. And then feel bad when I take a dose after I've missed one... haven't really noticed weight gain I believe though. I do feel nauseous sometimes as well as headachy and dizzy and some concentration problems. It was suggested that I take it at night, before bed. Then you sleep through the symptoms!

Do NOT take it while drinking, especially at a higher dose. I've heard bad things about that.

As for the mouth pain (? you said dentist right?) ... well, not experienced that one, but maybe you're not taking to it well?
