second brushing today

skipped yesterday

running into an issue with finding time for the 2nd brushing now that I am committed to drinking 1 gallon of liquids per day and especially since I now drink highly acidic liquids (water with lemon juice and apple cider vinegar) that can destroy my enamel if I brush immediately afterwards. For brushing, I need to find time which is at least 30 mins after last intake of liquids and 30 minutes before the next. It is non-trivial.
