Advice about after Wegovy

So I'm one of the many who went to refill their script and got the sticker shock for how much Wegovy is. I'm working with my dr and my insurance, but if that falls through, what have people been doing to keep the weight off without the meds? I've lost like 30 pounds, and I just can't go back. I'm afraid the hunger is going to come back and get me, but I may try something like intermittent fasting or something. Just curious what everyone else who can't afford it or has come off it is doing to maintain or lose.
