Healing DOES happen during the small tapers and that is exactly the point.
I agree, you should not updose everytime you have a symptom. If it is minor and workable, give it a few days and see how it goes. If it is calming down...hold longer. I preserved actual updosing to those times I knew I was not going to come out of it witrhout a prolonged-drawn out hold where I couldn't function properly.
My last "true" updose was going from 1 to 1.5 to 3mgs. I did try cutting from 2 down to 1.5mgs and within a day I was shot so that;s where I went to 1.75 instead. I don't really call that an updose. I just quickly changed the amount I was going to decrease.
