a Few Issues About Sleeping

Hello, new here and need help! For a few years now I have been facing some issues related to sleep. First off, I find a sleeping pattern very hard to obtain. Even if I go to bed early, no matter how tired I am, I tend to wake up around 4:00am and I am unable to fall back to sleep until it is time to wake up. I have read this is a sign of insomnia, but not sure. Not sure of any cures or help on this one, as it does not affect me every single night - but once or twice per week.

Secondly, and more importantly, I can not remember a morning where I woke up not feeling sick. My mouth is completely dry, my throat hurts, and my stomach feels nausiated for a few hours. I am currently trying to stick with a diet, and I find it very hard to eat in the morning. I can not eat more than a banana without feeling sick. Also, lately I have noticed the top of my throat is actually starting to hurt. I can press on it with my tongue, and it feels sore and or bruised.

Does anyone have any information or suggestions? I plan on going in to see my family doctor soon, but would like to know more before I do.

Thanks :d
