Leptopril is a useless product and will not help you lose weight. It's just marketing hype. Plus, it contains some ingredients that could have side effects, including the funny feeling you have.
I agree with Jane, you might need to revise your eating plan. Also, you didn't mention how much exercise you do, and you have to burn more calories to lose weight. Check out our Support forum and post your average daily menu and exercise routines, and you'll get a lot of feedback that will help you get started
