It takes an absurd amount of kratom to reach that level of withdrawal, though. In most cases the kratom withdrawal is akin to cannabis, where one suffers from insomnia and irritability for a couple days. I used to take roughly 10 grams daily for about a year, and had to quit cold turkey when the state banned it. So, I know first hand how it goes. Though I have heard reports of people suffering from worse cases that were similar to opiates when they were taking upward to an ounce daily, which like I said, is an absurd amount. These days I take 3 to 4 grams of red vein Indonesian (a highly potent strain with long lasting effects) once a day, and don't have any sort of withdrawal when I have to go a few days without, nor do I have to redose throughout the day due to the potency. Less is more when it comes to kratom I've come to find.
