It's tempting to try to detox from Ketum at home. You can attempt it, but it's much safer to stop using it in a controlled and monitored setting.
More than anything, your goal is to ease Ketum withdrawal symptoms. It probably won't help to purchase a detox kit at your local pharmacy. However, you may want to at least speak with your medical doctor about your intentions. They may offer you medication to help with your symptoms, or suggest over the counter drugs that may help.
The best way to get withdrawal relief at home is to stay comfortable. Make sure you have plenty of water and other beverages on hand to keep yourself hydrated. Ask a friend to stay with you as you detox.
