Power pumping question

I got food poisoning a couple days ago and I didn’t pump because I had excruciating pains in my stomach. Of course my supply quickly decreased and I would like to get it back up to where it was before so I am power pumping every hour for about 15 minutes, however I want to know how many days do I have to pump every hour ? I read that it does take a few days for the power pumping results to arrive but im not sure how many days I have to do this. I’m getting half of an oz every hour .... lol it’s so frustrating but I guess I’m doing the right thing by alarming my body that I need more

Please let me know how many days do you recommend I do this
