They say that some people can get short term muscle aches. I don't feel any or enough that I would notice. My neck and shoulders feel the same. I've been feeling more awake in the morning is all. I used to sleep one REM cycle when I was at my raw best and then go in and out of the second REM cycle with lighter sleep, lucid dreams, doing dream work, meditating etc. I've missed that because since I went that period where I didn't sleep for half a year taking care of my mother I've been sleeping almost too solidly sometimes past the 9 hours the two REMs take and then had to do my dream work and meditation after that. Half a year without meditation or dream work in itself was a big change - let alone the sleep. I needed to make up for all of it sure - but I kept hoping things would eventually go back. Since the first night on a slant I've gone back into my old pattern of sleep which feels healthier and happier with my dreams more vivid again and I have more energy first thing in the morning. Last night in the second half of the night I felt like I was slightly vibrating. It was a weird sensation - but not an unpleasant one. I felt like I could have gotten up and started my day after the first REM cycle if I wanted to.
I think how you are going to feel might have to do with how many toxins your body is holding onto and suddenly now able to get out during the night through the kidneys according to what I've read. People can hurt, have headaches, be achy etc. The only differences I've felt are thirst, more yellow pee and what's in the above paragraph. Maybe I don't have as many toxins because of my diet but I haven't felt anything negative at all - only positives as I perceive them. My feet if anything have been feeling better. They have been achy lately and now they are much less so.
Last night I didn't slip down the bed either - which was good.
I think my body is already adapting.
Jessica - they say that you are supposed to do it slowly and gradually raising your bed up little by little. My husband is doing that but I went straight up to the top level the first night. I bet if you did it more slowly it wouldn't feel like when you're sleeping outside on a hill. I've done that too and it was really freaky. This doesn't feel so freaky - maybe because it's my own bed in my own room and so familiar all except that one thing?
