Fluoxetine
"I am female 65 yrs, 157 cm, 58 Kg.  A lifetime of depression and anxiety, taking 20 mg Prozac daily for 15 years seemed to help a little but panic and anxiety was same as ever, terrible.   As well, I was addicted to Zanax 5 mg per day for 14 years, which is a high dose and apparently considered by our government, a nasty drug to be restricted now.  After 2 months of taking 60 mg Prozac I am no longer needing any Zanax at all.  Weight is very stable, I am feeling normal in every way and sex with my husband every few days, is still wonderful and exciting.  No doctor ever suggested the increase in dose of Prozac to help anxiety until very recently.  That's why we need the internet."
