Hey Sporty_g, I have been having exactly the same problems for about the same length of time. Can't get to sleep until around midnight, often later. Can't get up in the morning till around 7:30 or 8 -- making me late for work. My doctor shared some things with me about 'sleep hygiene' that I can send you (5 pages), but you can probably get the same info from "Sleep Disorders for Dummies" http://www.amazon.com/Sleep-Disorders-Dummies-Max-Hirshkowitz/dp/0764539019/ref=pd_bbs_sr_1?ie=UTF8&s=books&qid=1204512631&sr=1-1
Many things can come into it: your schedule, your eating habits, your caffeine intake during the day, stressors, unusual crises, etc.
I would not recommend any of the OTC products like Sominex or Tylenol PM -- they're junky and will leave you feeling extremely groggy the next day.
Some natural products that are good are Valerian
(an herbal supplement -- get a good name product), and 5HTP
has been re-released, but a bottle can be expensive (around $25).
Prescription supplements are available: I used Ambien
for a while, and it was okay. Lately, I keep Sonata
on hand, and have been happy with it. Lunesta
is also out now, but I haven't tried it. The only thing with these prescriptions is that long-term use (a month or more of nightly use) can open you up to some strange side-effects -- the only one I've heard about is Ambien inducing sleep-walking problems. I never used any of these prescriptions for more than 3 or 4 nights in a row, so I can't speak from experience about side effects.
As for me & my current insomnia problem, I'm not sure, but I have some theories.
I'd be happy to talk to you personally on the phone, or even by email, and share some ideas with you. Email me if you want to.
Good luck to you.
