Weird the 100 mg ones are more expensive. My doctor just started me on them. I was really weirded out on them at first..200 mg's first go around. I found out if you take them with Strattera, Effexor, and Xanax... you may get side effects.

I had this feeling like my chest was gonna explode and I would pass out, so my doctor cut my doses of strattera back, and now all is well. Would you believe I still fall asleep on provigil sometimes?? good luck with it this time.
