I've been taking it daily for years now, but very low. I take it for ADHD since its mildly stimulating but also calming. If you take a lot of it I know it can affect your mental fogginess, also sex drive . It isn't as strong as opiates by any means but it is pretty good and can be another thing to rotate. Kratom is available , it should be fine to order online. I can give you some sites but not sure if they are in Canada or not.
