I’ve been taking Fluoxetine on and off for the last twenty years. I think it’s also known as Prozac. I had problems getting used to it - felt very drowsy and disorientated to start with, but that got better. It’s important to have regular GP check ups whilst taking it, as it can have some physical side effects in some people. Coming off it is difficult as withdrawal can make you feel very sick, but as long as you follow GP guidelines on gradual withdrawal you should be fine. I find it the best of the SSRI’s for me and usually lifts my mood within a few weeks of starting it.
