I like your doctor! I am going by side effects. For 3/4 of the days on 5 clicks, I did not have bad side effects. On 6 clicks, one day was bad and today was not too bad. I am going to alternate and 6 for a week then try to go to 6. Yes I would be happy to get to 6 for a year and then get a scan. Good luck to the tortoise!
