Don't recommend someone take codeine for kratom withdrawals that's horrible advice, kratom withdrawals are not even remotely bad enough or do they last long enough to do that. Kratom isn't an opiod you're just opening up the potential for full antagonist addiction which is night and day difference, as a former oxy/heroin user codeine is a slippery slope and the withdrawals are the same it's literally just morphine at a crappy conversion rate and a really bad effect on physical health.
