Has anyone heard of/tried the ephedrine free Trimlife? If so, has anyone had good results from it? I've been trying to lose weight for almost a year now. Trimlife has a 30-day money-back guarantee(don't they all) and I'm thinking of trying it. Xenadrine EFX did nothing for me. I'm 230lbs., hence the screen name wannab160, and I need something pretty powerful. Any suggestions?
