depression
"Started taking Wellbutrin after the birth of my first child 9 years ago.  I had had a history of depression since college, and had tried different medicines but could not manage to take anything consistently.  Postpartum depression and alarming thoughts about harming my child were the final straw.  My doctor put me on Wellbutrin.  I did have some initial side effects, including trouble sleeping and lack of appetite.  I also had shaky hands for the first couple of weeks.  I have stopped and started a few times over the years thinking I didn't need it, but always ended up back on.  Each time I re-started I would experience the side effects for a few weeks, and have finally learned to just stay on it."
