I have done the same. Cut sugar drastically, work out almost everyday and try to make myself uncomfortable whilst working out so I am more comfortable under load in the world. Also to prep this olde body for the next decade. Far better overall to start 10-yrs earlier than later.

I have a home gym now, but back when I was trying to solidify my workout habits I had to will myself to workout as I passed the gym on the way home from work. Wanna race home to party? No, go workout. Feeling lackluster? Doesn't matter, workout. That extra push I gave myself back then worked (and felt great) and now I strive to get that workout in and feel bad if I don't.
