Will I experience a rebound effect if I don't get the diet injections?

Summer arrived a while ago, but I’ve hit a wall with my diet. I don’t feel like exercising, and controlling my appetite is so hard, so I’m considering weight loss injections.

There is so much information on the internet, but now that I’m actually about to try it, I have so many questions, such as whether there will be any side effects or if I will gain weight back if I stop.

I heard that among the types of diet injections, Wigobi, Saxenda, and Maunzaro help you feel full, so they naturally reduce your appetite.

An acquaintance of mine got a diet injection.

I heard that after getting the injection, your appetite decreases and digestion slows down, so you feel full quickly even after eating just a little. They say the craving for spicy food or late-night snacks also disappears.

If I stop getting the diet injections, will my lost appetite return? I'm curious if I'll experience the yo-yo effect.

I am also curious about whether there are any side effects and the cost per session.
