Back to the gym?

Now that one of my offices is officially open and I'm somewhat stable. I'm thinking about rejoining my gym. I've gained way too much weight the past year after working so hard to get it off. And medication doesn't help. So when I went to court yesterday, I remembered that the gym that I was a member at is right there so I'm debating on going in and taking a look at prices for membership. I need to get rid of this weight and my videos and DVDs are not helping me lose it-keep it stable yes but not losing it.
