Sleep.

what time are you getting up? The only way I managed to combat this going from working nights to mornings was make myself get up at 7am every morning, no matter what. DO NOT NAP! Soon your body clock will change but you have to get through the whole day and by 11am you're bloody shattered!

Sounds like you have insomnia to some degree. I went through a sleep study a few months ago and have a slight insomnia issue. I have "restricted" sleeping times. I have to go to bed at 11 pm every night and get out of bed at 6:30 am every day -- 7 days a week....no naps during the day either. If you do that for about a week, your body may adjust. If it doesn't, you may want to go in and talk to your doctor about it. The key is to make yourself be in your bed ONLY during those allowed times. Even if you don't sleep at night - you CANNOT take any naps during the day.

Another tip -- if you cannot sleep and you are lying there for 15 minutes, you should get up, do something around the house that you do NOT like to do for about 30 minutes...and then go back to sleep again.

I wish you luck - cuz I know how much that SUCKS!

Sleep is the holy grail for me.... I hate it.

I have so much energy that I often struggle to fall back asleep after a midnight poddy break.

Try melatonin. It's available over the counter and is inexpensive.
That's what our physician recommended for my teen son (who has trouble falling asleep) and my husband (who falls asleep and then wakes up at 3am and can't get back to sleep).

You're not going to magically go from going to bed at 2 to 11. You need to work your way backwards. I recommend every couple days go to bed 15 mins earlier but get up at the same day each day. No snooze button!

When I had insomnia issues, mine were caused by stress. I had trouble shutting off my brain.

Any light in the room disturbs my sleep. - Blackout curtains ($20 a pair) solved that problem.

Any noise, even after I'm sound asleep, wakes me. - a $10 fan left running gives me enough "white noise" to overcome outside sounds.

A period of preparation helps, along with a set bedtime. I used to stay up till 2-3AM every night. Now I am in bed by 10PM, and up by 6AM. I start by sitting quietly with a cup of relaxing tea about 30 minutes before bed (like Sleepy Time or Chamomile.) I lower the lights, and turn off computers and TV. I meditate or read. The stimulating screens of TV and internet are a problem for me.

Once in bed, I shut down my brain by blocking any thoughts that come in. This is where knowing meditation techniques helps.

It does take practice. I feel your pain. Keep trying.

I've had insomnia since I was a little girl. I've gone through numerous studies and tried everything but still, no luck.

Most people find by going to be at the same time and getting up at the same time with no naps your body should adjust to sleeping at normal times.

If you have more energy though, use it up someway and you should become drowsy.

I am the last person to talk to about sleep because I have the world's WORST sleep habits. I go to bed about midnight and wake up at 6:15. I enjoy a 45 min. nap in the afternoon if I can swing it. I have gotten in that silly habit of sleeping on the couch and not in my bed, which can't be a good thing. But my issues were even worse than what they are now a year ago. I was actually falling asleep at work and doing crazy things when I was asleep at home. Come to find out the meds I was taking for blood pressure has a side effect of drowsiness. I was taken 4 pills a day. I changed doctors and the new doctor couldn't believe I was taking this certain med. I switched and never fall asleep in the middle of the day (unless I want to) and I feel a ton better.

So...are you taking any medications?

Download some sleep hypnosis apps and listen to them. They really help although they seem cheesy. The Paul Mckenna book and CD that was reccomended earlier does work too. I hate going to bed, I stay up way too late every night regardless of what time I have to get up in the morning, the hypnosis stuff is the only thing that helps me.

So do I, although I've gotten slightly better.

As a sleep deprived law student (yes this is being posted at 2am) I take a lot of melatonin... its a natural sleep aid you find in the vitamin section of Walmart - cheap and easy but make sure you get the 3mg pills or youll be taking 2-3 of the regular... hope this helps Im in love with it! You dont wake up feeling bad either!
