No, because I never got into a consistent habit of it and just stopped trying. Either the weather wasn't suitable or the sun was in the wrong position when I had a few minutes to do it or I'd forget. The dermatologist also wanted me to face those surfaces with the plaques/nodules toward the sun, and that was never terribly convenient when I had nodules or plaques on the bottom of my feet or my knees.
There are days where I bask in sunlight and others where I'm mostly in my hidey hole (esp. with the pandemic), so nothing too consistent. My post wasn't too clear about that, but yeah, I had stopped the dermatologist treatments (other than T-Gel shampoo) prior to the Vitamin D thing.
