Take a couple of days off. Thats what I did. My first day going cold turkey was right before I had a 4 day weekend, but I had been tappering for a few days so i was in withdrawal on that day.
Kratom really helped for these few days in terms of the physical symptoms. For me days 2 and 3 tend to be the worst. And yeah day 4 aint not picknick at all, but once I am over that 4 day hump, I think the actute withdrawal symptoms are over.
