First I started taking MSM - just mixing 1/2 tsp in my water (I use a 16 oz glass and ice and put it in every time - 6 or 7 times a day) which totally fixed the constipation. I was just SURE it would also fix the rectal bleeding, but it didn't. THEN I started the keto diet which totally reduced the amount of stools - WITHOUT constipation - but ALSO fixed the rectal bleeding!! Plus, even though I haven't been strict with it (they call that lazy keto, LOL) I've lost 20 lbs. Plus, I've regained a lot of strength in my muscles (getting old, you know how it is) Just wanted to pass this along!!
I suggest you do the MSM first - before you do keto - to sort of clean yourself out. It's not like diarrhea or anything like that, it's just a good experience, all the way around. One good poop takes about as long as it takes to pee!
I gotta tell ya - that MSM thing - THAT was amazing! Plus it make water taste like the good water they have in Germany! It's dietary sulfur so I guess it sort of makes mineral water, I don't know - but it's really good water!
