Can supply drop a lot in one day?

I had food poisoning Thursday night and was sick all night and most of yesterday.

I breastfed when I could but my other half gave my 8 week old 3 bottles of milk from the freezer and I only partially “replaced” one of them.

I feel a lot better today myself but my son has been the fussiest I’ve seen him yet and I wonder if my supply has been messed up from being sick? He’s constantly wanting the breast. I’ve hardly been able to eat so I know my calorie intake has been quite low but I can’t see 1-2 days being that harmful to supply?

I had so much anxiety with my first baby around supply that this time I’ve really focused my mindset on supply/demand and my body will do what it needs to do that I’ve been relaxed up until now.
