The way you reduced it is amazing.
As my AN is 1 mm x 2 mm, I must admit I wouldn't mind to be able to do the same...
Apparently, you did "nothing much more" than eating healthy, drinking a lot of water, cycling, walking a lot, doing some relaxation and avoiding smoking and alcohol?
Which is already very considerable and very brave, considering you had absolutely no guarantee of any results.
I'm already doing absolutely all of it, except walking 4 miles a day. Which is something I really dislike. Of course I would do it, if I could be sure it would make a difference. Anyway, I'm doing some daily sport instead, something like 20 minutes in an intense way.
Your optimism maybe also did something. It's another element too difficult to reach for me.
Do you think it would be interesting to take some supplements or daily aspirin in my situation? Apparently, you never did?
