Thanks for the support and concern, Wild_Coyote. I thought of stopping it but it's just two days and there would probably be risks with stopping it suddenly too. It's been a few hours since my last post and i've been relaxing at home with my dog and feel some better. Actually i feel remarkably well for someone who has had three hours sleep in the last two days. I think as long as i keep to myself this weekend and take it easy i will be okay. What a crazy thing tho: i go from chronic oversleeping to acute under-sleeping!
