I started taking Prozac around new year and lost about a stone (I think) in the first few months. I can explain this as my appetite fell away so I was definitely eating less.
For about the last 3 months, my appetite has returned and while I'm not eating more than I did usually (pre ADs), I'm eating normally for me again.
I still seem to be losing weight though (or at least not putting it on). I don't weigh myself so am not sure how much, but clothes are getting looser.
I'm pretty active. Don't do gym exercise as such but do a lot of walking (ie. trekking type stuff). I probably drink a little more than is recommended.
I'm not particularly stressed at the moment. Anyone any ideas of what might be behind it? I've no other identifiable symptoms or problems.
