depression
"I LOVE Prozac. I have major depressive disorder and general anxiety disorder. I was on Lexapro for half a year, and despite not being a teen or young adult I had my first ever suicidal thoughts. On the Lexapro I felt sedated, I gained weight, and I was still depressed. It did help with anxiety, but instead I was often nauseated. 
Now after 2 weeks of Prozac, world of difference. I'm smiling, motivated, looking forward to the near and distant future. I still have some mild nausea, and it's not as good with the anxiety or insomnia. Still, it's great for me because I'm motivated and energetic enough throughout the day to make myself tired enough to sleep, and I'm better at dealing with stressful things."
