First of all, congratulations on staying on plan and not binging for 3 weeks. That is a great accompishment.
There are no rules saying you have to weigh yourself while eating better and exercising. Some people weigh daily, some weekly, some monthly and some not at all.
The quesion is, how do you feel? Are your clothes looser? Is it easier to get out of bed or a chair? Do you have a little more energy?
As for exercise, you can always workout at home. If you like to walk outside, you might enjoy Leslie Sansone's walking dvds. I started working out with those and they're great.
It is raining here, too, in sunny California. I love it! ♥ Everyone is sleeping here and the house is so quiet. Perfect ME time. ツ
Please don't feel you have to weigh yourself, especially if you feel it could lead to a binge. Don't let that darn scale dictate your life. You are worth more than that.
Ciao bella!
