I started with 200, and redosed with 100 every 2 hours or so, for a total of 600mg. I had a great time. Although it was super crowded... Raves are so much fun after 2 or 3 when the drunk people leave!
I will note that at one point, i was definitely overheated. I started to feel woozy, and my skin felt like it was on fire, similar to having an awful sunburn. I drank a couple bottles of water, and I was as good as new! Stay hydrated my friends.
