Yeah, cleaning up your diet is really important. Stevia is a good substitute for sugar. Fruits are also awesome to help your cravings. Lysine rich foods should be a basis also. The only thing that really has a lot of arginine is wheat products and a couple fruits (oranges mainly). But, you can get grains that are much more healthy and just as tasty. Amaranth and quinoa are awesome and have almost equal arginine and lysine.
