How many Day 1's can there be?

I think I have tried every diet there is. I have been just buckling down at the gym and working it, and I have not lost a pound! I work out 7 hours a day 4-5 days a week. I went to see a doctor about this and she says it is because my primary doctor put me on Actos. Actos makes you gain 20lbs! Bastard. The cool thing about all this is that I have not gained 1 pound since going on Actos because of my exercise regime. But does it take that much to maintain my weight. I am idling at 182.4 for the past two weeks. In my eyes, Actos is not winning. I am keeping up with it!
