Yes, some meds, can and do cause weight gain. I refused to allow that to happen to me. I drank water as if I were a fish. I gave up soda, made small changes in a permanent way. I had never accomplished this before in my life no matter what the diet was. Small meals, lots of available fruit and healthy snaks to nibble. I lived life obese until I made these changes. I lost 60 and continue to keep it off by dong these few things. I did not excersise, calories in, calories expended. I had to cut calories if I didn't excersice alot. removed all fats, except the real foods, I use real butter, milk, cheese, all in moderation even ice cream. That old saying of moderation is key. good luck to all of you who are wanting to change. I promise you, if you do those few things and stay with it, you will loose. ginnie
