"prozac is an amazing medicine. i was severely depressed and saw no light at the end of the tunnel. my anxieties and depression were slowly killing me. i couldn&#039;t eat, sleep, or be still with myself. my doctor prescribed prozac. first 20mg then 40mg. it took about 30 days before i noticed a big change in mood. my situation never changed, but the way i looked at it did and i felt hope and got a warm feeling. the side effects are manageable. my libido has decreased slightly, but i am still able to achieve orgasm. i have not had any weight gain.  i&#039;ve been on prozac for about 8 months now. it&#039;s been a life saver for me. i just started cbt counseling with a psychologist so i can learn to think and react differently to/about some things."
