Hi everyone! So I was on tirzeptide starting dose and I wanted to switch to Reta. When I tried switching over I had a racing heart for a few days and barely slept. I know this has been mentioned as a side effect. For reference, I had a 5mg bottle mixed with 1ml of bac water. I did a shot of 12 units on a 1ml insulin syringe. I tried to break it up and I did 5 units then another 5 three days later. I didn’t have a racing heart then but I didnt feel it working at all. I continued using it then used the dose form 5 units to 7, then the racing heart started. In this a side effect that will go away or not?
The tirzeptide worked well for me except i would get blurry vision 2-3 days after my injection which is a big reason why I wanted to switch. I don’t know what I should do. Has anyone had any of these side effects?
