I have been in a similar situation to yours, so I feel for you and the understand how frustrating it is. The sleep specialist that I saw told me that my body clock might be out of kilter. The way to reset it is to set the alarm for the same time every day and get up then no matter what time you went to bed. As soon as possible after getting up, go outside to get some light on your eyeballs. Hope things come right for you soon!
