Not really, because I don’t go straight to eating. After getting out of bed I first brush my teeth (or go to the toilet, depends), then I shower. Afterwards I make breakfast. So between brushing my teeth and eating there’s roughly around 20-30 minutes. With a glass of water before taking the first bite there is no taste left.
I’ve thought about brushing before or after breakfast for a while and neither way seems great. Before is great because you lose the bad breath from the night. After is nice too, except you like coffee for breakfast. General rule is always: Don’t immediately brush before or after eating, especially if you eat anything acidic, that fucks your teeth up.
