It increases immediately and takes a few days to settle back down. After quitting my weekly average slowly continued to decrease. My RHH is a very consistent 46 bpm now and it was consistently in the low to mid 50s during the months/years I was routinely drinking on the weekends. Obviously there are other factors like fitness, sleep, general health, but I was monitoring the numbers on a daily basis and the trends became really clear.
