So, as per the title, I started Mounjaro last night. When will I start to feel different? I know this sounds ridiculous, but I cannot find anything on line. When I did the injection, there was a little bit of fluid at the top of the needle (as they said) but I could not see any bubbles when I flicked the tube. I then injected it, but I have no idea whether there was anything that was actually injected. So I don't really know whether I have started it or not, and if I have, how long before something happens! As I said - I know it sounds ridiculous.
