Hello Kell and the rest of the gang.
Yes I've had lots of them going back to about 1973. (aged 14). On average a rate of about 2 to sometimes 3 a week. Sometimes they last seconds only though. Sometimes that horrible grabbing feeling is so bad before it happens I just have to shrug it off. Last night I was really tired after a 7 day 10 hour shifts week and within 5 minutes of getting into bed it was like i was attacked by these awful grabbing and squeezing hands, all around the legs. Was so bad I had to get up out of bed for a few minutes. I must admit, I think they scare me more than anything else to do with this subject. Once you are out, it is a joy, almost uplifting experience though.
