"i have been on antidepressants for 5 yrs and several of them made me gain weight and i always had this feeling of shakiness.  my dr switched me to a combo of wellbutrin xl and prozac 20mg.  i&#039;ve lost like 15 pounds and feel way better!!  made such a huge difference for me in how i feel about myself.  i agree with others that have posted, i only take brand name meds.  i&#039;ve heard so many issues with how generics don&#039;t work as well.  to me, to feel better and finally be able to enjoy life, it is worth it.  my two cents..."
