Oh bother.....
I am dealing with sleep related issues myself. In fact I have been since around 20 December.
I'll go two to three nights absolutely no sleep. Then I'll suddenly fall off asleep, usually in my easy chair at some odd hour (when I really don't want to sleep). I'll wake up usually late in the evening or in the middle of the night. Thus, my circadia rhythm get thrown off. Then I am on this pattern for a few days. Then it's back to no sleep for a few days, and so on and so on....
The problem is is this is taking a toll on my system. I tried all of the common OTC remedies and none worked. In the past when I have had similar problems (not as bad as this) my doctor prescribed some different medicines but two didn't work at all and one put me out for two days and I was sick for a week afterwards. I reduced the dose to half and then 1/4 and it still made me sick. So the only medication that works makes me sick. Ugh! So the medication route is useless.
I have tried the stay up 24 hr+ to reset my rhythm but I usually either get sick and have to lie down (in which case I go to sleep) or I fall off asleep with out knowing it (did this on a bus once).
Right now I am on a wake up late afternoon evening/up all night, then sleep all day pattern (at least for a few days). I really don't like this as it exascerbates another issue I have, seasonal depression. I find that I need natural daylight in order to avoid being depressed. Being that this time of year daylight is at a premium, ideally I need to be awake right before sunrise (around 8 in the morning). Unfortunately, I am waking up just prior to or after it goes down so I am getting no sunlight.
Also, these hours are limiting what little social interaction I do have, as most of these people are at home winding down for the day. Not to mention the places I like to visit are closed or closing (ie the libraries, the museums, etc). It also makes it difficult, if not unsafe to do any decent bicycle riding or go on long walks.
Anyway, enough of my rant, this isn't Speakers Corner at Hyde Park!
Any ideas or suggestions would be great!
