going through insurance but can't get an appointment until March25

My regular doctor gave me a prescription for 2.5 and a coupon he had so I could get it for free. I filled it in December but didn't start until two weeks ago. At the same time I signed up for a program sponsored by my insurance to get tirzepitide, plus dietary guidance and monitoring, but I found out after I had done all the paperwork that I can't get in to the medical for almost two months. My free mounjaro is going to run out, and I have lost about five pounds so far, I don't want to start regaining at this early stage. Does anyone have any ideas for a way for me to get a quick stop gap to stay on ***something, anything***? that isn't going to cost a fortune? I am just despondent over this!
