My IBS, after an elimination diet and a couple weeks on Ultraclear, has turned out to really be an inability to digest protein and fat, something I\'ve probably had much of my life. Can\'t believe the tremendous change after doing the elim diet and the Ultraclear. So with the 5-HTP, with no appetite, the ND was encouraging me to eat as much protein as possible. Not only did I have the effects of the 5-HTP, but eating more protein really exacerbated existing conditions. He put me on a soy protein drink which I really had a problem with, as the nutritionist says, most people like me would.
