During the night I feel weird and scared like uneasy on my legs difficulty in sleeping, I was on medication etizolam .5mg 20days, clonazepam.5mg 20days then clonazepam .25mg 20 days now I haven't taken it for over a month, and I'm taking escitalopram in morning and melatonin 5mg at night for 3 months, am I facing withdrawal symptoms or it is due to Irritable bowel syndrome?( Ecg,2decho,Tmt, blood tests,bp,sugar, all are normal)
