In my own experience, I'd say it took at least two weeks for it all to 'gel.' I mean the physical addiction to opiates/PAWS was gone within 48hr....but the other INCREDIBLE changes that have resulted in a wiser, stronger, HAPPY EVERY DAY, can only eat healthy foods, even is a better guitar player.....MGS.....did not begin right away....I definitely went through some difficult moments of transition (not related to cravings, or opiates....just the realizations that the way I had been living was not right for me, but felt lost at first as to what to do next) because my everything was defragmented and then factory restored...it took a couple weeks for the personality that I was before becoming consumed with addiction came out again....and then blossomed.
I'm telling you, reread what I said about MOST IMPORTANT EXPERIENCE IN YOUR LIFE. Sorry for the caps, I know people hate that. The reason ibogaine fails for so many is they do not have 'follow up care' and I think most people do need a facilitator of some sort, or 'Shaman' if you will...to tell them the things I am telling you.
I hope you can take even more than a week off. I'm sure in the end, the loss of labor will make up for the gaining of life.
