My favourite

Though I haven't had any for a longlong time and now there's all these different strains that confuse me. I used to use the solid extract (it was just boiled down leaf, there was none of this 3x, 5x, 15x stuff then). I used to boil it so it disintergrated then cool it in the freezer. It's really bitter so tried out a few "recipes". I found it a lot easier to drink cold so I'd cool it, mix it with icecream and milk, sometimes some chocolate milkshake powder and cinnamon. Cinnamon still reminds me of it even now. Then I'd drink with a straw slowly, but I'd still start to feel my mouth numb as I was drinking.
I can only tell you how it made me feel, I bought it for sleep at first but it didn't send me to sleep. It kept me awake but in that nice dreamy, sleepy awake so you're not wishing you could sleep or anything.
Taken during the night and no sleeping: nice afterglow the next day.
Staying up all night and then taking in the morning: really nice synergy with sleep deprivation. It helped with social anxiety as well, I was happy to talk to everyone and craved company but not in that obvious "drugs" way.
It also only "worked" when I was already fairly content with myself/life. When I tried to take it for anxiety or depression it made me irritable. A couple of times it made me sick, no idea why, same batch, same dose. And a couple of times after I did sleep I woke up with a headache. But these were rare downsides compared to many other drugs.
