I was thinking last night about all this (I'm an insomniac, I think a lot in bed, lol) and I remembered that the week after I had my amalgam filling shaved, I had real bad pins and needles in the night. I was on holiday so thought it was an unfamiliar bed, but it was terrible. One night I had to get up and go on the balcony and another time I had to walk around the hotel at 3am in the morning. Since then my anxiety and compulsions have shot up aswell and before the summer I was tryiing everything to help from magnesium to milk.
