Weight loss is a side effect of Prozac. She may want to talk to her dr to see if a change is necessary. There are also other things that can be taken for anxiety and nerves for the short term.
I have seen medications work really well for mental conditions. The trick is to try and figure out why the problem is occurring and getting rid of the problem. Sometimes that is possible, sometimes it is not. Just popping a pill for anxiety isn't the solution long term. It is a tricky area to diagnose and medicate. Just my two cents.
Thanks. Someone did finally tell her that her weight loss could be related. In this case we know the cause, a life changing move. I'll mention making a change if she thinks she really even needs the drug to begin with.
