A lot depends on how mentally dependent you are to it. I find its the mental aspect that is difficult. Its hard to understand how numbing it is mentally until you stop taking it. You will have some anxiety and depression, probably some random mood swings. From a physical perspective, your stomach will be messed up, loose stools (take lope), watery eyes, sneezing, restless limbs, it might be hard to regulate your body temp (you might experience random sweating and cold flashes), insomnia is common.

Are you able to tell the people you are going on vacation with that you will be going through w/ds or are you going to have to try to hide it? I hate being around people while going through it. I personally wouldnt want to waste a vacation going through w/ds but everyone is different when it comes to it. It also depends on your bodyweight, 8-9 grams might be different for someone that is 150lbs vs someone that is 220lbs when it comes to w/ds.

Ultimately I think it comes down to the mental aspect. For example, if someone is on kratom because they used it to get off opiates then its going to be a lot more difficult to get off kratom and live a clean life vs someone that doesnt have a past with addiction issues.
