Fluoxetine
"I had been on Prozac for three years and gone through a lot of hard times. It helped when I was splitting from my ex, Lost a job, got into some legal trouble, lost my license, and had to move back home.  After getting back on my feet again and getting my license and a job I decided to ween off of it...bad idea..I became more and more stressed out and had very bad stomach issues that I never had before.  After about three months off 40mg a day I had a huge panic attack and days of not eating or sleeping.  I have since gone back on 20 mg and hope it starts to work soon. I should have never gone off this medication it saved my life once and I hope to have the same results again.  I was happy, able to take things much better and be myself."
