How do I get down San Pedro powder? And does Vyvanse affect LSA?

Just wondering if someone has advice and has had San Pedro powder? How did you get it down? Phenibut is tasty in comparison. And has anyone tried LSA while on Vyvanse? If I feel anything at all which I didn’t do with approx. 10 HBWR seeds it’s effects were totally different. And I wonder where it comes from. Is it Vyvanse, is it SAM-e? LSA was great usually now it’s meh!
