Dont reinstate [...], imo it'll only make things worse in the long term. Im the same with sleep, hardly any for months so i know how you feel. I took some rescue doses but it has only prolonged the wd, i wish i hadnt but was desparate at the time. Ive been taking 2- 4 mg of meletonin now for the past 4 nights and it has help me get some sleep, about 4 hours broken, maybe a bit more, at least its something. Im hoping this will i prove over time, its abdominal pain that keeps me awake.
