as a part of the ritual fast prior to cactus use, i exclude the use of any and all drugs. pharmaceuticals arent in my diet so ive never had to consider it. however, i am a regular coffee drinker and abstain from it and other plant drugs on the day of the experience.
its not contraindicated, in the amounts you are taking it wont really affect your experience
you may not feel the need to use kratom habitually as you were post experience.
above all, listen to your body
