trouble refinding motivating

i lost 25 lbs since last december with calorie deficit and some workouts (not enough, definitely could have been better with exercise) before my wedding, and now that it’s passed, i’m having trouble becoming motivated again to continue. i’ve already gained back 6 lbs since my wedding a month ago and i don’t want to gain anymore. i’m still 17lbs from my initial goal and looking for some advice to get back to it without a big event putting pressure on me. i’m still tracking calories but very loosely and go over almost everyday. i just don’t feel urgency right now to be disciplined with myself but i really don’t want to reverse all my progress. any advice to goal setting and follow through? thanks!
