Desperately Seeking Skinny

Hi all I'm new to this and just started my duromine 30mg on Tuesday, so far I've lost 2kb probably water retension. I've read alot of great success stories and I kinda feel I'm falling behind. I'm even tempted to take a double dose so 2 x 30mg or is that dangerous?? Has anyone ever taken it in to their own hands and taken two? Am I expecting too much too soon?

I am quite desperate as I got down to my ideal weight of 60kg years ago and now I'm double at 120kg I'd be happy at 70kg.

Thanks Lovelies
