Oxypowder might get you going again, but just be careful that you don't have to take that all the time. They are an honorable company because they will refund your money if you don't like it so it might be worth trying. (I ordered it once, but when they sent me another order that I didn't order, I refused that and sent the other back and they did give me a full refund.)
Just remember that everybody's system is different and what works for me, may not work for you, so it is just a trial to see what works when you try out these alternative methods.
