MrsD-Thanks for info, now I am worried!The neurologist put me on this dose when I was taken to the ICU,and put on life support,ventilater,13 years ago,and did not ever mention taking me off of it,even when I saw him last year.I will ask him about Zanaflex.I got more nerve damage 2 years ago, when I fell and was knocked out for 18 hours,woke up, and the leg I had been laying on, became paralysed from knee to toes,they think because of previous nerve damage.Now that leg hurts alot more than the G.B.S damage.
