A few weeks ago, I started supplementing between 500mg and 1000mg of mixed magnesium per day. I've noticed that I feel calmer, but I seem to feel colder at the same time. I have an internal "shiver" and if it's cold outside, my index fingers often turn white. In the morning, I tend to feel warm enough, but as the day goes on, I cool down. If I smoke marijuana, or drink alcohol, then I feel warm again. Likewise, if I eat alot of sugary/salty /fatty food, then I warm up, but I think that might be an inflammatory response. What's the likely explanation for this?
