anxiety
"Just finished my first week on the generic form of Wellbutrin (bupropion 150 XL) and have to say the first few days were tough:  dizziness, anxiety, and muscle pains.  But now those symptoms have mostly gone away.  I do feel amazingly clear headed and have lots of energy.  My appetite is gone so I hope to lose about 20 lb if possible.  I don't feel the need to drink at all (used to love my wine every night!)  The strange part is most people talk about insomnia and vivid dreams.  I suffered from those before I started this medication!  And now, I sleep a full 7 hours, have no trouble falling asleep and don't remember any dreams when I wake up!  I really like this stuff!!"
