How to start Mounjaro and looking for some advice ?

Hello there. After discussing it with my doctor for ages, I'm officially ready to start my Mounjaro journey. I'm honestly a bit nervous about the whole process (especially doing the injections!), but mostly I'm just excited to finally get going. The biggest hurdle right now is that everywhere local to me is completely out of stock. A friend suggested looking at online pharmacies, and I'm planning to get my Mounjaro sorted through https://www.medsforless.co.uk/mounjaro/. Has anyone had experience ordering from them for their initial prescription? Also, please hit me with all your best tips for surviving the first week!
