Use peppermint oil, diluted within lots of olive-oil(minimum 1:10 ratio) in a warm/hot bath, sit in it for 20 minutes minimum, and make sure that the stuff is put in the water early and splash around so that the oil does not remain only on the surface.
Other than that, try eating less per meal. High-meat involves predigesting the meat before it even reaches the mouth, so, yes, that should reduce gas.Of course, this might be due to detox. Are you still consuming cooked foods as well? Not a good idea, in the initial stages of going RVAF, especially.
