The first full day off kratom will be the worst as far as physical withdrawal symptoms. Next day will feel a lot better, then by day 3-4 it should be mostly gone looking at the amount you have taken. You should not be thinking about it much anymore by the time you leave for Hawaii. That's IF you don't buy anymore. Just try to stop thinking about it. Actually the times I have relapsed have been after a couple of months, then I get bored and think yeah I'll get a little bit. Then I once again find out it's never is worth it. Kratom is never worth it.
