Tips on waking up when dealing with severe insomnia?

I have delayed sleep disorder and a very erratic sleep pattern, so I'm usually up for 2, 3 days and then end up falling asleep for 4-8 hours (sometimes longer). When I do sleep, It's deep sleep so I don't hear the alarms I set on my iphone, ipad, alarm clock, watch, etc. Because of that I've completely screwed up my education, work, social life, and health.

I know the best way to ensure waking up is getting enough sleep, but I'm incapable of doing so. I'm hoping someone has some helpful tips.

So far, I've been told taking ambien speeds up your sleep cycle and makes it easier to wake up after it wears off (it's usually 4 hours or so).

Try these tips of mine: and before going to bed avoid thinking that will make you feel excited. Ok?
Here it goes again:
- turn off the light when going to bed
-don't drink water it will awaken you
-listen to a very sad music, feel it's loneliness, just reminisque all your sadness in life. Try starlight memories by study music project, search it in youtube, the trick there's lonely people tends to sleep more. Just play the song repeatedly and you'll see that you're sleepy nuh.
-avoid using devices and any things that emits light when going to sleep.
- so goodluck. That's my trick when i'm having an insomnia. Try to discipline yourself too.

Stimulus Control Therapy: creating a sleep environment that promotes sleep
Cognitive Therapy: learning to develop positive thoughts and beliefs about sleep
Sleep Restriction: following a program that limits time in bed in order to get to sleep and stay asleep throughout the night
Relaxation techniques, such as yoga, meditation, and guided imagery may be especially helpful in preparing the body to sleep. Exercise, done early in the day, can also be helpful in reducing stress and promoting deeper sleep.

Behavioral therapies alone may not be enough. Treating insomnia with medication is the most common treatment for these sleep problems, particularly once a combination of behavioral approaches has been tried

Get perscribed adderall. Makes me the most alert and focused person in my 7:30 lectures. All my classmates must think I'm a coke head.

Since you have an iPad and an iPhone:

I recommend you try these apps:

1) Progressive Alarm Clock

The progressive alarm clock app emits a sound which gradually increases in loudness, allowing you to wake up more easily

2) Glen Harrold's Sleep Well Hypnosis

This uses 'hypnosis' to guide your body to sleep, and includes a 20 - 30 minute relaxation tape

3) Brainwave's Binaural Beats apps

Uses binaural beats (used for meditation and relaxation) to assist in falling asleep
