Hey Kairdex. I CAN RELATE 100 PERCENT. I am a person who is cold ALL OF THE TIME. But I almost always have night sweats!!!! ***! I am also one to fall asleep like clockwork at 11. I just say, Oh its 11, time for sleep. And I don't even struggle to fall asleep. Stay asleep was my problem- which is probably why the Ambien didn't work- it just KNOCKED ME OUT but didn't take care of the waking up in the middle of the night. I'm not trying to tell you take sleep aid- especially if you don't want to. I just really don't want you to write them off. My sleepiness (which is was my #1 reason for seeking help) got RIDICULOUS in January. I sought help maybe in March or so. Through everything, I noticed that I was getting fragmented sleep. I knew this for a fact because I am one of those who looks at the clock when I awake. SO i would see and it was 2, then again at 5 or just before. I kinda hate my job, so I'm sure it may be some low kind of anxiety. But like I said, the Lunesta has kept me sound asleep through the night. I was literally sneaking in labs in quiet rooms at my job (shhhh, don't tell anyone!

).
Sleep deprivation is a wicked thing. It's hard to catch up when your deficit is so great. You can try changing your diet and exercising... Some people feel a change with these simple things. I did not.
I really hope you get some rest. Sleeping through the night is awesome

. I didn't even notice I WASN'T sleeping through the night till I started a sleep journal. I kept telling the doctor, I need help staying awake, not sleeping! I'm a pro at sleeping! But apparently I wasn't getting the right sleep. My matress SUX. So I'm also in the process of saving up for a really good one.
Good luck!
