I have been a kratom user for a while and have been through the withdrawal symptoms many times before. I can only describe it to be like a hangover after a heavy night of drinking that lasts for about 2 days. I use kratom over long and short periods; I have found that pseudoephedrine alleviates most of the withdrawal symptoms related to kratom; the only drawback is that pseudoephedrine has its own withdrawal symptoms. Give it a try!
