Losing Weight Top of year.

I have been wanting to lose weight, actually lots of weight. I was looking at changing one of the meds I was on, but insurance said, no. So now I have to find the best diet supplement that I can. At one week I have lost about 5 pounds so far I am working at losing more. I would like to lose really fast that is of course not so good.
Well I hope that you have a most happy day.
