I know I'm a bit late to this discussion but this is something I have struggled with for years. I have been on a yo-yo gain/regain cycle for about 6 years and really trying hard to break it.
When I started losing weight seriously back in 2009, I weighed weekly because I felt that weighing in more frequently could be depressing with daily weight fluctuations etc, and the general consensus in the fitness community was that weighing in more frequently could be misleading and counterproductive. However, I found that this (weekly weigh ins) only worked when I was consistent and gung-ho in the beginning (i.e. first 6 weeks or so of healthy eating and exercise), because I was losing rapidly. But when I started to become complacent because I had a bit of success or wasn't able to stick to my nutrition/fitness plan (another habit/tendency I am trying to work on breaking), I started to skip my weekly weigh ins because I couldn't face the number I would see (which would usually verify that I wasn't doing what I should have been or set out to do). I did this once during 2009 and found I re-gained nearly 7lb that I had lost [blogged about this in my 3fc blog

Eventually, this became a slippery slope, like many previous posters have identified. By January 2012, I was pretty much back to the weight I started at in January 2009. Unfortunately, I attach so much *weight* (no pun intended) to the number on the scale that it can, will and has set the tone for my entire week and dictate my level of self esteem. Part of what I am currently working through is how NOT to be completely and utterly debilitated by that number, but instead how to use the number on the scale as (1) motivation and (2) a tool to encourage consistency in living a healthy lifestyle and being a healthy weight. Major work in progress.
Now (since 17 March 2015), I weigh in daily or at least every other day - 1st thing in the morning (after using the facilities) and definitely "starkers" as one previous poster has most eloquently said
This helps to keep me honest and a bit more focused.
This having been said, I have not weighed myself since 30 March due to some slip ups (late night eating is probably my *major* demon) and TOM, so I am gearing myself up for a weigh in this coming Saturday morning.
My ultimate goal is ~155-160lbs. My highest weight was 225, and at my last weigh in on 30 March I was 218. I would really like to be under 210 by the end of April.
I have purchased some size 14 clothes (I am currently a size 16+) which I am really hoping I will fit into once I am <210 or so. Hence my anxiety!
Wish me luck
