It doesn't remove the joy, just the need. The first thing I noticed after starting is I wasn't hungry all the time. That constant sense of hunger made me eat when I didn't need to. Now I can eat a nice meal, but much of the time I don't feel a need to eat, so I don't.

Edit just to add that in 10 months I've lost 40lbs and halved my insulin usage. That insulin is the pricy synthetic stuff (Tresiba and Novolog), so the cost of the mounjaro is probably close to paid for by that decrease.
