In December it was confirmed that I was suffering from long QT syndrome after I had a cardiac arrest at work. I spent 3 weeks in hospital but on returning home I have been suffering from severe restless legs at night in bed which has prevented me from sleeping. I am on a very low dosage of beta blockersl I have been to my GP who has prescribed me diazepam but to take one only when I need it. I really don't want to take diazepam . Anyone else had anything similar?
