Perhaps you have some health issues and should consider seeking medical help.
You're either physically ill, or mentally ill. If neither, then it's a lifestyle problem, not eating or not sleeping properly. If none of the above then you are just making excuses.
Quit moaning and just wake up when the alarm clock rings at the time you set it to.
SIX things to help you sleep and wake up feeling refreshed (as well as carrying out all the ideas suggested in various sleep hygiene (what a silly phrase) literature; particularly trying to go to bed and waking up at a set time same time each day (so easy to say, so hard to do!)
1. Avoid alcohol late at night - it is a stimulant (you may think otherwise). Nicotine also? Avoid exercise near bedtime.
2. Ask your partner if he/she thinks you suffer from sleep apnoea - check web sites for this, e.g. Sleep apnoea | Better Health Channel) - if you think you do, get it checked out at a Sleep Clinic (there are several in HK). Sleep apnoea is associated with other cardiac complaints (e.g. angina)
3. Don't use benzo's (e.g. temazepam, zolpidem) as sleeping pills for more than 2 weeks - you WILL become tolerant to them, if not addicted. Try not to use them at all?
4. Try yoga and relaxation
5. Try a "spray" on your pillow.. would suggest "Deep Sleep" spray/mist from Body Shop
6. Remember, you will catch up with lost sleep one day....... mentally tell yourself each night that (just as you can tell yourself to wake up at a certain time, and often do) that tonight you WILL sleep well
Buenos nochas...
