I have had trouble sleeping on and off for years ... post op it was even more problem and I tried several OTC products with no help ... prescription sleeping pills helped but left me groggy in the morning ... what works for me is Valium ... if I can?t sleep I will take one and it works well for me and no residual grogginess ... some doctors are slow to go this route as they can be addicting ... but for me, lack of sleep was not an option ... I wish you luck in finding something that works for you.
