Hiya Nitty,
Sorry - I don't know about any of the MAV meds but I've been on a medecine that made me gain weight. My GP wrote me a gym prescription so that I can go to the gym but for reduced prices. It might be worth asking your GP about whether this is avaliable in your area to help counteract any weight gain.

I hope you manage to find something that helps you.
Take care,
Clare xxx
