Have you tried applied nutrition full diet pills?
I found these when shopping last night and there was one bottle on the shelf so I decided I might try them. It says take 3 tabs, 45 mins before your 2 biggest meals. And it expands giving you a full effect, so you eat less. I put one in a glass of water last night to see what it does. And it turns into this gel stuff that yes it expanding quite a bit. Have you heard of them?
