Switching from gel to injections - any advice?

I’ve been using gel for about a week and realized having to do a task every day is NOT compatible with my adhd lol so I asked my doctor if she could switch me to injections and she already sent in the script! (She’s amazing and I’m lucky to have her.) I’m a little bit afraid of needles but I think I can get used to it. My wife also offered to help. Any advice or things you wish you’d known??
