Backstory:
I got some Calea Z. a while ago. I've done some research into it and I recently tried some. First, after an allergy test, I made a tincture. The first try didn't work, I blamed bad measurements. Next I adjusted the amount and still nothing. Then I made capsules. I started with 2 caps with around 500 mg each, nothing. Then I went to 6 caps, nothing. I tried a tea with 3 grams then I ate the leftover material, nothing. Then I went to 9 caps, still nothing. In fact in all of the tries I only had one recallable dream, far less than normal! For whatever reason Calea seems to be acting as a dream suppressant!

The questions:
Has anyone had this problem before (both dream suppressant and non-functional calea)?
What other methods are successful? (I've heard smoking is good but I'm rather apposed to burning my lungs. Is a bong effective?)
I've heard about reverse tolerance with Calea, is this usually the case when it doesn't work?
Does anyone have more information on Calea?
