PaulSB...it kinda crept up on over a week. About a week after I began with it the foot and leg cramps occurred less and less frequently.
Mo, it didn't help me sleep at first because I took my vitamins and the magnesium with breakfast. It was only when taking it after supper, which in our house can be 8:30-9, that I noticed my sleep was improved. Took a week for that too. I have no trouble going to sleep initially, but I wake up several times most nights and take a whiz, and then I start fretting about any number of things, and can't get back to sleep for a long time, if ever. Now I fall back asleep pretty quickly. I also think knowing sleep will return before long relaxes me and instead of clenching my jaw and muttering "gotta get back to sleep" over and over, I just sink back into sleep.
