They also cause sexual dysfunction while you're taking them. Not a problem I guess when you're overweight, but on weight...it's a huge problem.
That's not a common side effect, and I've been watching GLPs for years. In fact, it's more likely to cause divorces due to, you know, becoming more attractive.
Or put another way, "Let me pluck one of the rare side effects and make it seem like its a common one because I know nothing about this"
