Couldn't Sleep Last Night

I had a horrible time getting sleep last night. Normally when I go to bed I end up laying there for up to an hour. Which I really enjoy, just laying in my bed feeling really comfortable. Some times I listen to some mellow music and other times I just let the brain whine down thinking of some nice things. Last night though I just couldn't shut off my brain. I was just laying there for like 3 hours thinking about everything and anything wonderful and bad. It really wasn't until 5:30 or 6 in the morning that I finally fell asleep. Also adding to my restless night was I still have this terrible cold and it is really hard to breath at night even after taking a bunch of meds. So like every two hours or so of sleep I would endup waking up and then try to start breathing properly before I could go back to sleep. Also I was drunk before going to bed and whenever I have alcohol in me I end up with really abstract wired dreams.
