I've had problems sleeping for years now. Basically, I sleep badly. I go to bed quite late, any earlier is pointless, and it takes ages for me to sleep. When I do sleep, I wake up every hour or so and am incredibly restless. I seem to get in bad habits quite easily. If I end up having a seriously late night, say 4 or 5 am, I won't be able to sleep until 4 for ages. So, I've been trying to really sort this out and going to bed earlier, cutting down coffee/caffeine, no computer before bed, being more consistent with doing zazen, lots of water or herbal teas...But the problem is...I feel worse. I am absolutely wrecked every day. I also feel incredibly dehydrated. And I feel quite miserable. Quite simply...is it normal to feel so bad when you change your sleep routines? I thought I'd feel better. Any other ideas to help with the sleep issue? Thanks!
