Thank you. I had read that post and guess I'm a little slow. I thought magnesium helps with muscle tightness so it would help with the cramps I get in my neck and other areas. I would also love to get my bowel issues under control and have discussed the severe constipation. Trust me we have tried everything. In the hospital they had to give me enemas to go. The body is so screwed up from years of the ed still though healthy weight. I guess it takes time. So the slow mag is the best for what I'm wanting it for? The initial dose is 2 and is there different amounts in the pills?Mrs D what benefits should you see so you know if you feel good or not to take more?Why do people take the kind I bought then?
