Aripiprazole (Xanax) is commonly used as a trip killer in the psychedelic world.

Just be mindful that depending on your dosage of Xanax as well as your tolerance to it, you are very likely to experience diminishing effects when consuming psychedelics. If it's possible, you should pick out a time to trip and skip on your medication so you can achieve the full effects.

But please take my advise with a grain of salt. If you experience severe anxiety, it's very possible that LSD might enhance the anxiety more to the point where you have very uncomfortable thoughts and feelings.

If you do decide to skip on your meds and have a bad time, you can always take your prescribed dose of the medication to effectively end the trip in less than 30 minutes.
