cheers man 
I found the first month or so pretty shit tbh - knowing my habits and that it could all go tits up at any moment. gets easier and even enjoyable once you get into a routine and create little milestones for yourself. like, I want to run this distance or I want to lift this weight. also use myfitnesspal to track calories and exercise.
scheduling treat days every week is probably the most important thing, actually.
honestly, if I can shift a few pounds and peel myself from the couch, anyone can. rooting for you man
