Few things I tried to overcome GAS:
Photography - didn't work for me (a much more expensive hobby)
Sports (swimming) - it also didn't work (whenever I'm tired, I'll always end up browsing the net)
Other musical instrument (drums) - wrong move, I doubled my GAS.
Frequent night outs with friends - I always tend to pay attention to the performers gear and performance.
My girlfriend told me that I'm going to be a daddy –Automatic GAS Free.
