Can someone give me some pointers on starting out with magnesium sulfate injections? My doctor is willing to prescribe some. I know you have to put them in your butt, but I wanted to hear the experience of others about the starting dose. Is a 200mg injection suitable? The reason why I'm doing it this way is that I want to have an accurate measurement of my intake. I have taken epsom salts baths and done magnesium oil but they are imprecise. Years ago I looked into this but for some reason I thought mag sulf was only available by IV. But now it seems you can take the same formulation and inject it IM. I've read in a few places that you should dilute it with saline or taurine so that it doesn't burn so much. For someone with CFS, is my starting dose reasonable? How often? I have a good MD but she does not know a lot about my condition outside of standard protocols (which are leaving me wanting). So I'm kind of on my own with this. I am definitely lacking mag in my life. Body tightness, muscle spasms, anxiety, and feeling tense are all signs. I also feel like mag helps me with my depression. Thanks!
