These are classic signs of detoxing and adjusting to the raw diet so there shouldn't be anything to worry about. Don't anguish over losing only two pounds, it will come off when your body is thoroughly cleansed, which could take several months to a year. A good way to ease digestion is to soak your nuts and seeds, as well as eating a smoothie for breakfast. You could also try food combining which should help with the pain and bloating, for instance don't mix fruits with nuts or starches. Good Luck!
