Have been sick during running, then 2 hours later, put it down to the fact I hadn't had enought to drink that day. We were on holiday at the time and were out touring Skye in the car. Had a couple of cups of tea, then a couple of shortbread biccies with a coffee when we stopped for a break. Went straight out for a run when I got back. Was okay for the first 20 mins then had the urge to vomit. Was slightly sick. Felt a lot better continued on with my run. Drank a couple of glasses of water. Felt awful when I had a shower lay down on the bed, then just as father in law went for his shower I got the urge to puke again, threw up in a carrier bag out of cottage window. Poor hubby, mum in law and father in law got my daughter for the rest of the evening as I felt sick and had a headache. They put it down to a tummy bug, I knew it wasn't have done it before when I have not had enough to drink and or eat. Lesson learned always have a bottle of water with me now.
