Hello, I'm 24 years old. I drink buttermilk with salt in copper mug (stored for 3-4 hrs in mug) 2 days ago. When I drink after that something wrong went inside of my body. I'm getting pain of my lower abs and I get vomited at 4 am, after vomit it some relief from that day, onward getting little pain in lower abs and also not getting any hungry eating single meal for a day. Is anything wrong please tell me. My friend take same one glass he also feel the same thing at that time from morning he become normal. But I take 2 glass (may be over dose) still in trouble.
