A common side-effect of people who frequently use Ketamine for recreation purposes but don't use the insights gained from such sessions to help them heal from previously unaddressed trauma or make progress on the things holding them back in life (e.g. alcohol, opiate, benzo addictions, etc).
Friend A: I don't know, man; I always feel regretful after large seshes of K.
Friend B: Last night, you said you finally understood why you place artificial limits on your personal and professional progress and that you wrote down some info to help you remember that and implement positive changes in your life.
Friend A: I don't know, man; I think Ketamine is just Regretamine.
