Honestly I was finding the last 15 lbs to be stubborn, and had a borderline mild sleep apnea test that meant my doctor offered it and my insurance would cover it. I also wanted to see what all the hype was about.
I forgot about sleep apnea. I was struggling with adjusting to CPAP, and never really succeeded. After losing a fair amount using tirzepatide, I did a repeat sleep test and my sleep doc gave me the green light to put the CPAP in storage.
I was beating my head against those sleep issues for years, and had multiple doctors sit down and tell me that I probably "just had a high sleep need." In the end, I'm not sure whether it was the thyroid or some vitamin deficiency (before the multivitamin I was on iron, C, and D separately), but it turned out to be very treatable.
