Sorry you're not well op and hope you feel better soon.
Your baby will be well fed and healthy, your condition will be treated and your boobs will stop leaking!
You will remember what it's like to not smell of milk.
It's really quite nice to wear whatever you want too instead of having to think about if you feed in it.
It may be different for different babies but anecdotally, mine was far happier, less gassy, and slept far better after I switched to formula.
The constant searing pain in my neck and shoulders diminished in a couple of days and was gone in a week.
My boobs stopped hurting.
Dp did a few night feeds so I got a few nights of unbroken sleep and actually bonded with my baby more when I wasn't a miserable, irritable, sleep deprived bitch than when I was bf because I could concentrate on lovely my ds is instead of crying because I needed to sleep.
I could have the odd drink if I fancied it and as much coffee as I could drink.
Also worth nothing I think that it's perfectly ok and normal and natural to feel a bit sad about not feeding for as long as you had hoped to (i certainly cried a few times when I stopped). That sadness will pass in time and you will see your baby is healthy and happy, with a healthy mum who is able to care for them because she got the treatment she needed.
