I would say I'm a heavily internet user, I can spend 10 - 16 hours easily on days that I don't have school. Obviously my body is not taking this abuse very well. When I was a teenager to about 21 -22 I used to exercise often, go to the gym train. Even if I was using the internet and porn all day everyday there was always a little spot to keep my body in shape. Sadly no matter how much you take care of your body, spending about 10 hours online everyday will take it's stole on your body. So at 24 I injured myself while doing exercise. The doctor told me it was strain from moving my right arm too much ( like using a mouse too much ). Xrays and ultra sound shows that have herniated discs in my neck and that my posture was off. I was supposed to heal in about 2 months ( with therapy), but since I kept on using the computer all day long ( doing nothing of importance) not only did I not heal, but I made my injury worse. So here we are now with me having lower and upper back problem. neck issues, right arm issue, shoulders issues and starting to have the same issues in left arm. I also have chest issue. Now I know that sound bad but I'm still functional, but I can't lift anything heavy, I'm also out of shape due to training a lot lot less. I'm slim with a belly and a little bit of man boobs . My body could still recover, but unfortunately for me my addiction is just too strong. I'm student in graphic design, yet I was a heavy computer/internet users before that. I'm planning on stopping using a computer altogether for a minimum of 3 months in may because I'm really needs to get this addiction over with. I got nothing from it, only health problems. I only wrote about the physical part of my issue, might do the mental part later on anyone else has some major issues due to their computer/ internet abuse?
