Switching to Mounjaro 2.5mg - help!

What’s it like for those who’ve switched?

I stopped Wegovy 5 weeks ago on 2.4mg. I tried it twice and had bad side effects. BUPA suggested I try Mounjaro and had a call with a nurse to go over administration (I don’t remember what she said). I imagine I give myself the shot like I did with Wegovy.

I was sent Mounjaro 2.5mg. Is that high to be starting on? I am surprised they didn’t suggest a lower dose for this switch. Any thoughts or advice would be totally appreciated. Thx. ☺️
