try to plan for a 3 day of shittyness, with as little work in those 3 days. Get a lot of water, and some klonopin or xanax with maybe some ambien. Tylonal (i get headaches coming off opiates), dont expect much eating or sleeping, which is why ambien can help.
Your not coming off a big amount but you should still feel a bit of a w/d. Good luck.
