Has anyone vomited black bile on ketamine? I only use K on an empty stomach and have now twice vomited a thick black liquid on the comedown (the only two times I've thrown up on K)... My interpretation of this is that my gallbladder is secreting excessive amounts of bile while on K which is backing up into my stomach, but I'm having a hard time understanding the lack of color to it. There's been no hue to it, not even a dark shade of green. The volume on the first occasion was ~10ml and the other (following a more intense experience from a higher dose) ~20ml. The first happened ~15 minutes after my last insufflated dose for the evening, the more recent about an hour after IMing. I'm a light user and am healthy. Generally, black vomit indicates GI tract bleeding, but considering the lack of negative after effects I've experienced, or anything else pointing to a serious GI problem, I'm leaning towards a less dire explanation, though I'm not exactly comfortable with it
Opinions? Experiences?
