I read some calamus experiences and was taken in by stories of seeing feries and easter island statues, and I passed off all the sickly trip reports as people with weak stomachs.
So just to be safe I started off with only 2 1/2 grams. I capsulised the root powder into five size 00 capsules (this comes out to be almost exactly 1/2 a gram per capsule).
I swallowed all 5 capsules on a somewhat empty stomach and waited for awhile. About half an hour later I notice that I feel weak, a bit shaky and slightly strange, nothing fun at all. So I told myself that I'll try a larger dose tomorrow. A couple hours later I went and ate chinese food. I came home feeling absolutely horrible. I wasn't just nausious, I felt shaky and weak and even had a slight headache all at the same time. It was absolutely horrible. Normally, I don't mind blowing my groceries when i'm on something, cause I usualy feel so much better after I puke. But this wasn't like that at all, I didn't feel any desired effects, it's like I had just taken some pills that gave me the stomach flu. I threw up all the chinese food that I had just barely eaten. Which was absolutely horrible cause it was all chunks, and I hadn't drunk much liquid with it so I thought somthing was going to get stuck in my thoat and I was going to choke.
After that I felt a little better and I drank a bunch of water. Then I started feeling horrible again, so I would have to go right back to the bathroom and puke up all the water I had just drunk. I would do that again and again throughout the whole night, until eventually I was puking yellowish-green bile. I puked until 2:30 AM, and then I finally fell to sleep still feeling like shit. I puked a total of 23 times that night! It was making me cold too cause I would drink cold water, and it would cool off my stomach, then before my stomach could warm the water up, I would puke up the cold water and drink more cold water.
I still have a respect for this plant, but it is definately somthing that I will NEVER try again, it was absolute misery.
Peace
