I think you should weigh yourself as much or as little as you want, if you feel that its driving you crazy then take the scale out of the bathroom and put it somewhere your less likely to use it. I have herd of people putting it in there car because they were less inclined to go out and get it just so they could weigh themselves.
That being said, like many of the people have already said weighing yourself everyday is not necessarily a bad thing as long as you can understand and accept that fluctuation are completely normal. I weigh every day under the same conditions, after using the washroom, naked, on the same tile in my bathroom. Its rare for my scale to show the same number two days in a row, it's usually either slightly up or slightly down... Usually up. I don't let it derail my progress or make me upset because I know that its usually water retention. For example yesterday I weighed in at a new low of 133.8, today however I am back up to 134, I am not upset about it in the slightest. There could be several reasons for this I didn't drink enough water last night, had something a little to salty or there could be no reason at all! It is what it is
Several people on 3FC have made graphs of there weight loss, you should consider taking a look at a couple. You will see all the little fluctuations like on sontaikle's graph. Its really eye opening to see that everyone has those fluctuation but over time you still see a downward pattern. I also agree with runningfromfat, there is no rule stating that if you weigh once a day your going crazy and obsessing. I hate it when I hear people tell me I am obsessive because I weigh every day, obsessing has nothing to do with it. Different things work for different people.
