It takes time for the SN to circulate. You are ingesting 25 grams. Only 1 gram actually needs to be absorbed, the rest is for redundancy. If you make it 10 minutes you might already be past the point of no return. If you're nearing unconsciousness, so like 30 minutes, then consider yourself dead. The necessary SN has already been consumed. Throwing up the rest of the won't change anything. This is not financial advice and I'm generalising, I don't have the exact details about your digestive system.
