anxiety
"I am 23 and have had extreme anxiety/panic since around 20.  I am super sensitive to meds/ side effects.  I have tried so many AD and none have worked.  Recently I have tried Remeron but had to switch due to drowsiness- I have hypersomnia.  Lexapro by far has taken away my worrying mind more than anything which is amazing.  The first month was pretty horrid besides that though.  Constant nausea, yawning, worsened anxiety at first, headaches.  I still have some nausea and now I have noticed extreme drowsiness again. I really love how it helps my anxiety, but (like always) the side effects really bother me.  Try it out, get thru the 1st month. If you don't have bad side effects its the best anxiety med I have ever had.  Good luck!"
