I don't know if it would help, but usually muscle twitching is a sign of magnesium deficiency. Stress can cause deficiencies in zinc, magnesium, vitamin B6(and the rest of the B's), vitamin C. However, if you have kidney problems, you probably shouldn't take this supplement. A decent reference is the book: The Doctor's Guide to Vitamins and Minerals (c. $6). It gives symptoms of deficiency, overdose, and toxicity. Good luck!
