Geez, I vote cut back, ween yourself off..... maybe 2 x's monthly then 1 time a month, get out there and spread your wings, attempt to fly... with the caveat that you can return for a tune up if needed. Knowing you have the option of returning to the nest, may make the termination feel like more of a indefinite break. Good Luck.

PS. A set stop date is so rigid , it doesn't have to be like that.
