Many medications for bipolar can cause weight gain, (like zyprexa which I'm on) the weight gain may have nothing to do with the time spent sitting playing the game ( I'm not sure, I think you were blaming the game).

I think we're programmed to play games, many animals have contests, largely non-violent displays and battles to determine who's boss, in my opinion sports and games are remnants of these instincts (yes I made this up but I do believe it).

I'm not saying it's wrong to want to quit or cut down, just there are good reasons why it is hard, not because you are "bad", "weak" etc

When I quit my addiction to smoking I needed substitues like popcorn, bad, but not as bad as smoking, now 4 years later cold water is still a bit of a substitute for smoking.
