"i was recently put on effexor and i have seen a huge improvement in my motivation and mental clarity. i actually want to get out of bed and do things. i actually want to work out. i don&#039;t want to eat all the time anymore. i am severely obese and now after being on it for almost 2 months i have lost about 10 lbs, and i feel great. i haven&#039;t noticed any detrimental side effects. it has actually increased my libido, too. i will post if i see any bad changes.
