I still weight myself the same time every day ONCE a day AND I also use Trend weight. It links into my fitbit account and has a "Trend" so that even if you weigh yourself and you gain you could still be trending down.
Here is MY trendweight to show you what I am talking about. So in some cases I don't mind gaining the next day because on the curve I am still heading towards my goal
I can post the link because I need to make 8 more posts. I will show you when I have reached that point
