Back on topic, has anyone ever eaten food which made your whole body feel great for a while? Depending on the person's diet, eating some healthy seeds may have a similar effect.
While I have no interest in what the OP has to say on the subject, the fact remains they're convinced they're having 'a reaction' anyway. The diet angle is about the only thing I can come up with. Except perhaps some sort of contaminate.
I remember someone gave me a Sugar Cube at a Pink Floyd show.I dont know why but my whole being never felt so GOOD!
