spend only one hour at a time on the internet

I’m going to do this to beat my addiction. I’m not going to limit my internet time to any one specific amount of time at this point though. I would like to come online when I feel like it, but am only able to spend a maximum of an hour on it. After that I have to stay off the internet for at least another hour. I can do things on the computer that are not the internet, like edit photos, organize photos, or make little movies. I’d like to see if this helps keep me off the computer more and get me to actually DO stuff.
