Before I started Lipotrim, I was totally convinced I would never, ever lose weight on it, that, of course, was providing I could actually stick to the damn diet. I have lost weight and I am continuing to confound myself, although my best friend was convinced I'd do well on it.
So when you go to the pharmacy on Friday, SD, you WILL have lost weight. It might only be water for the first week, but you will lose. As you said, taking in only 500 calories a day, you just cannot not lose. I look forward to seeing your first weigh-in results. After that, you will lose fat. All that stuff you've been carrying around will disappear forever.
BTW, I was one of those people with several identical items of clothing: six tops from Bon Marche for work; expensive M&S jeans because I knew they would fit without trying on. Today I bought two more pairs of jeans and a top from Tesco. The jeans are size 16 and were £7 each. They might not fit me now but I KNOW they will fit in a couple of weeks.
