I had the terrible gut pains, throwing up and running to the bathroom when I got up to 16 drops, but I only took MMS once a day. I usually fight throwing up too because it's very rare that I get that upset and I am not used to it, but that time, with MMS, there was no way to avoid it! My stomach hurt so bad it scared me. I didn't feel good for a few days, but the worst of it was over in a few hours. I really think it may have been a combination of MMS and the chicken dish I had at a restaurant that day...maybe the chicken had salmonella and caused the MMS to react twice as strong.
I haven't used MMS since, and it's been 4 or 5 months approximately. But I may try again after a while.
Most everyone says that they have had an improvement in bowel movements long after stopping MMS. It helped me too.
