"for years i struggled with depression unknowingly since i could remember never thought to take any action though until a few tragic events happened. then came the suicidal thoughts and such so i went to a doctor and got this prescribed to me. prozac 20mg, i can honestly say i have never felt so good in my life. haven&#039;t had any suicidal thoughts or anxiety or very much depression. the only thing i can say negatively about this medicine is that it did decrease my sex drive and left me feeling quite tired and with a lack of energy when i first started taking it lasted about 2 days. ever since then no such problems have occurred except for the lack of sex drive. thank you prozac you honestly saved my life."
