I gained weight, too. I only drink water and coffee for the most part, and try to eat healthy. I do enjoy salads now, and try to get a decent breakfast in every day. It seems to keep the hunger at bay much better.
Also, early on I switched to taking Lexapro in the morning, and do 2 cups of coffee in the morning back to back. It seems to keep the sleepies at bay. But... I'm also a coffee addict, so it balances.
