I've been more careful this week! I've not gained weight

NONE of the gyms will let me join for one month for less than 65 + joining fees! The local council subsidised gym has a minimum of 3 months for 150. I simply can't commit to going on weeknights, I often travel for work and work up to 7pm most evenings. This month I'm doing training and I have shorter hours. But I can't sneak in a gym for one month because they all want to make me commit to months of fees that can only be cancelled by sacrificing a baby goat at precisely midnight under a blue moon. With the signatures of five witnesses. In blood.
