The pain was tremendously reduced when I woke up the next morning since that post.
Today is the 3rd without Activated Charcoal, and the pain is almost gone, only little whirling in the stomach 2-3 times, and I mean a little, still can feel it though. Each time took just about 4 seconds.
Maybe there were really toxins somewhere in my gut that reacted to Activated Charcoal. Though I don't know if that's good or bad news since it gave me freaking stomach ache lol
