Some days two or three times, sometimes I'll go two or three days between visits.
Once or twice a day for an hour or two. Way too much, but when I'm here it's very hard to leave for some reason!
Since Covid the check ups have been a lot more frequent. For better and worse.
Few times a week? Few times a day? Sporadically over the course of a couple of weeks?
I'm here a few times a day, but try to keep it to a minimum. sometimes I'll take a week-long (or longer) break.
