My Most Successful Attempt At Ssild, But A Major Fail.

I did exactly as the tutorial reads. I wake up after 4-5 hours of sleep, have a drink, get back in bed and begin doing the 'cycles'. I proceeded to do the cycles for around half an hour, when I started to get a numbing feeling in my arms and legs, and I felt that my mind was drifting off. I stayed like this for another half an hour, and then I just opened my eyes because I realised that this was going nowhere. Am I doing anything wrong? Is there something else I *should* be doing?
