I dont think I can do it (Seriously need help)

I don't think I can do it man honestly. I thought this whole thing was a joke. I've been researching and looking into this subculture for a long time. Today I was going to do what I do every three or four days: hook the laptop up to my 50 inch HD TV, grab the premium lube and go to one of the paid HD pornsites that I subscribe to for an epic sesh.

I don't usually do it every day, or even days in a row. But when I have to do it, I have to do it. Sometimes its multiple days in a row, but not often. Thats why I've often felt like I don't really have a problem. I mean haven't we dispelled the fear of masturbation as merely religious puritanism? Because if its a busy week at the office I can forget about it completely for five, six or even seven days (rarely) sometimes. But when I have to I HAVE TO.

And now, I dont know man, I haven't acted on my urges, went to this site instead, and I am feeling REALLY, REALLY weird. Like I feel like by body is vibration almost or something. Like my horniness energy is trapped and cant escape so now it is circulating throughout my body. I am honestly getting scared by this. I never thought I had a problem with this, but maybe I do, I dont know. This is really freaking me out. I think I might be sweating, haha. Maybe this is an addiction after all. Is this feeling normal? I'm twenty minutes into my NoFap challenge and I can't handle it.
