Should I quit tirzepatide?

I’m wondering if I should quit tirzepatide. About 2.5 months ago I started going to a lifestyle medicine nurse monthly, who gave me great tips on how to lose weight. She told me to count calories, carbs, protein and fiber, and to eat x amount of each of those things. She told me to do the Mediterranean diet and focus on protein. Within a few days of the first appointment I found out I was pre-diabetic and my cholesterol was really high. So I felt motivated and made a bunch of changes. I lost 1-2 lbs/wk for a total of 7 lbs the first month. I decided to start tirzepatide to help it go faster, and took 2.5 mg the following month and I did the diet like the previous month. Again, I lost 1-2 lbs/wk and lost 6 lbs that second month. I don’t think the tirz helped me lose that weight bc I felt hungry and like I still had food noise/cravings. It’s hard to tell if it was all me or the tirz. Anyway two wks ago was 4wks into taking tirz so I upped the dose to 5 mg and have taken that dose twice. Most of the weeks I’ve been on tirz, I’ve gotten nauseous for 30-60 min two days after taking the GLP. So that’s doable. But I got pretty nauseous for days 2-5 after taking it this last time, but it could be bc I’m on my period. I just feel like since I got on tirz, I have heard many people gain the weight back if they quit or that they have to take it forever. It just feels like such a big commitment and that I may have rushed into it bc I was losing weight on my own. I’m just wondering if I should get off of it while it’s early and try to lose the weight on my own before I get really dependent on tirz. I sorta wish in hindsight that I had just waited to see how much I would have lost on my own bc 1-2 lbs/wk wasn’t too bad. By the way, I also lowered my cholesterol from 315 to 210 in just 3 mos from diet. So that’s good.
