any vitamins that work well as a appetite suppressant?

The best appetite suppressant is getting sugar out of the diet. Sugar makes you CRAVE more food especially if you eat it in the morning.

Glucomannan is a soluble fiber that gives the feeling of fullness when taken with water, and is helpful in suppressing the appetite.

L-Glutamine (amino acid) is good for carb and sugar cravings.

take out anything diet like diet soda. I'm almost 50 pounds lighter and I'm never really hungry and I swear one reason is because I never drink diet soda anymore.

Borojo supplements have helped me in terms of curbing appetite and cravings - see the Wiki entry in here for more information
