question: Hello doctor,This all began about two and a half months ago when I went through an extremely stressful period. I started having trouble sleeping. The stressful period has long passed but my sleep still is not back to normal. For the past six to eight weeks, I can easily fall asleep, but wake up every two hours or so. I wake up and get back to sleep within five to 10 minutes at the most. But it is very annoying. I wake up in the morning not feeling refreshed due to the fact that I have woken up four or so times throughout the night. I have no trouble getting back to sleep. So, I do not believe this is stress or anxiety related. Any ideas?
