I am on my 15th Day and I love this drug. I do have intense, crazy and very frustrating dreams and I feel sick if I don't eat first (vs. with food) before taking it... but I have not smoked. Still think I want to at times but I just don't actually do it. Now... I noticed late last week that I now have a grey stain across my two front teeth that was never there before. Anyone out there have this problem? Figures I quit and now my teeth look bad. Wondering if its a side effect...
