IS it Wrong ?  

Is it effecting other areas of your life?

My fiance does the same thing. Playing video games until 3am, gets up for work at 7:30am. Doesn't affect him one bit. If your life is not falling apart and you are not making yourself sick from not getting enough sleep, there is no problem.

then i am insane...

Nope if you are are an adult and not hurting your self or anyone else and do have priorties in your life and do get out some and get the excersice you are to get....have fun..I know some time I love sitting up and just doing things on the internet playing games, talking to people,,making new freinds around the world...lots of things it is calm and peaceful at night and sometimes the only time to myself to be able to do get away from the real world...have fun...hope to see ya up some night

Take care of your health. How about your job? Are you sleepy at your job?

When your legs start to cramp, you've overdone it, and you'll need to take medication and take up a fun sport like walking in circles. Otherwise, the fantasy world is fine, as long as you pay your bills on time.

I do just the same. Most people think I'm weird or strange or whatever. But I know I feel comfy. I hope in the future it will only be a hobby, but as for now... Internet is my life. I don't see it as a completely wrong thing, though. Just look at this site, for instance. I think it's a great place to share ideas on lots of subjects, and you even earn something by it. I think the important thing is keeping in touch with reality and people. That means visiting forums and sites like this one. Talking, chatting, emailing... no matter what, but the main thing is interacting with people. I think that is enough not to make it "wrong".

Nothing is wrong, why would it be?

Agreed, if it's not affecting your life or health, it's just a hobby.

I do it, and i am sure many others do it also, You however, could be insane, you would have to get checked on that one.. Just keep doin what you are doin.. Alot of people do it.
