"i was on lexapro, effexor and cymbalta to treat my depression. all of these meds affect sexual drive and cause a gain weight (20-30 pounds). i also had a hair loss on lexapro, muscle pain on effexor. my doctor gave me wellbutrin brand samples for 2 weeks-150mg a day. wow, i started to feel a difference on the second day, my mood was excellent, i had a lot of energy, i could feel a joy from little things. the only side effects were: constipation and no appetite at all.
