Hi Anja, it seems like you genuinely need pain management as you’re still suffering badly. Have you spoke with your GP for other possible medications you could possibly take for your fibromyalgia?
As far as quitting codeine, it’s hard especially if you’re trying to mind your children and work. For that first week, you’re not able to function properly so be kind to yourself. You’ve gotten to day 3 which is amazing! Take each day as it comes and remember all the withdrawals are temporary! You can do this if you want! However, if you take another pill, that is not failing! It’s tough giving these up and can take a few attempts. I really think you need something else in place for your pain too.
Talking can really help. Not sure if your partner knows but having someone who knows can help! We’re here to chat and have a group outside this on WhatsApp if you want more support. I’m here on this forum too if you want to talk xx
