"i was on and off lexapro for many years, but i always felt tired. we tried a few combinations of anti-depressants but none of them gave me the energy i wanted--even with as high as 450 mg of wellbutrin by itself. i&#039;ve been on 20 mg of viibryd for the past couple of weeks as well as 300 mg of wellbutrin.  i now have the energy and desire to go to the gym, breeze through work and housework, and visit family and friends. my sex drive is slightly improved. i&#039;ve had slight digestive issues but nothing major. i hope things continue to improve. i&#039;m impressed so far. i&#039;ll give an update as to my progress in a couple of months."
