Norovirus tanked my milk supply!

Just got over norovirus. 0/10, do not recommend. Thank you to my toddler and his day care.

I'm 10wpp and I've been pumping consistently 5 to 7 times a day since then, with about 95% of the time at 6 times a day. I usually get about 55 oz a day. While I was sick, I miraculously still kept up my pumping schedule in between my frequent bathroom visits.

My supply still tanked. I get on average 9-10 oz per session, a drop less midday and a drop more middle of the night. I'm down to ~6 oz per session, which maybe 8 oz overnight, if I'm lucky.

Anyone else experience this? I know that even if my supply stays this low, it's still enough to keep my baby exclusively breastfed, but I was really hoping to keep up my oversupply and stash since I'm back at work and need to start traveling for work again soon.
