Ya know, this is a very touchy subject because so many bandsters have different point of views when it comes to the scale.
Personally, I weigh in once a week. There isn't really a wrong or right way when you should get on the scale. Its what you feel comfortable doing. Keep in perspective when weighing yourself daily, the numbers will change too. So, you really have to be mentally ready to handle the highs and the lows.
Now, I will also add that since you are 'newly' banded you should not be doing this. Your body now is going to take around 4-6 weeks to heal and is going through so many changes. Remember you have a brand new stomache now and your main focus is to 'heal'.
Best of luck on your new journey,
