Exercise really saved me--hiking, crossfit, just taking walks were critical for me to get the focus off food and I naturally lost weight and felt better.
Yoga was also a great addition--I was stiff and tense and yoga put me back in touch with my body.
All of these can be done free or cheaply except crossfit, but even that type of thing is do-able with online support and body weight exercises.
I am fighting a sugar issue right now myself again, and not surprisingly, it is worse because I haven't been working out regularly the past few months.
Low carb / Whole 30 helped me beat the sugar cravings before and lose weight quickly, so planning that again.
I think the body is used to the booze carbs which is why it can be hard to get established.
Great job on a month PG!
