Wegovy 1.7 for a while and starting feel hungry/heavy

I’ve been on 1.7 mg Wegovy for about 3 months now and I’m starting to feel anxious about my progress. I’ve lost close to 20 lbs (which I’m grateful for!), but I still have about 15 lbs to go and I’m worried the weight loss is slowing down. Has anyone here switched from Wegovy to Zepbound? If so, did you notice a difference in results or side effects? Also, was your insurance willing to cover the switch? Another thing I’m really anxious about — has anyone’s doctor taken them off the medication once they got closer to their goal weight? I’m honestly scared about what life will be like without it and whether the weight will come back. Would really appreciate hearing others’ experiences. Thank you!!!!!
