For the past couple nights I've been attempting WILDs. Last night I was completely still for about 2 hours, from about 1:20 am to 3:20 am. I tried to relax, but as time went on my body began to do the "test" to see if i was asleep or not. But it really started hurting with a pain in my arms that went on and on until it was unbearable and I had to stop. I kept holding out thinking it would go away but it wouldn't. Is this normal? It seemed more intense and prolonged than what people say to expect.
