I Work 3 Nights A Week 6.30p To 7.00a And

I work 3 nights a week 6.30p to 7.00a and I can't sleep during the day I have tried ambien, lunesta and tylenol pm and currently giving melatonin a try. My room is blacked out and its just like night time. I sleep great during the night its just during the day, used to sleep good in daytime but older now and only been back on night for about 1.5 yrs. Any suggestions?
