Hi there currently on 40 mg Citalopram for anxiety (have been on Citalopram for 5 years 3 years on 20mg and 2 years on 40mg.. Feeling flat at the moment .. thinking about switching to Fluoxetine .. Has anyone done this and how have you found it? I was on Fluoxetine a long time ago and think it gives you more energy.. as well as being good for anxiety.. If anyone can share experiences they have had I would be really grateful. Thanks.
