depression
"It is hard to judge this drug with others since it is the only drug I have used.  Having said that, it works.  My focus is better while I do not experience the same racing heart beats when stressed, and  I rush less.  Best of all, I finally quit smoking and this drug helps immensely with that.  I do not experience side effects, it helped to stablize my weight and enhanced sexual feelings.  My doctor reassured me that it is safe and I can continue to take it.
Most anti depressents are seratonin uptakes but this is a dopamine uptake.  My theory is we lose dopamine with age."
