Yeah I get it. There's also a wierd pain I get occasionally in my legs all of a sudden that makes me limp a bit cuz it feels so sore and tight, but that's something else I think.
I would say this shit is real, but it's more of a mindfuck than anything. I mean the more you think about it, the more it seems to last. But YES, it's a real bitch. I think it also has to do with circulation, you just need to move a bit more.
However, what prevents me from sleeping most is I can't stop myself from talking to myself in my sleep. My mind jabbers on without me sometimes. Sometimes I even repeat the same vulgarties over and over in my head, "fuck, fuck, fucken shit, mother fucker, eat shit, fuck, fucken shit, asshole, fuck, fuck,....." lol
