With you having to judge millions of children, that you need to get high just to stay sane; you get a pass.
But there is a general recommendation to not eat or drink for 15-30min after brushing to give enough time for the fluoride to bind to any exposed enamel surfaces. It’s also better to use a fluoridated mouthrinse over water, if getting the grittyness is what you’re after.
