Nausea

Thursday night was horrible. Halfway through archery training, I started feeling dizzy. It got worse as time went along and the shaking of the MRT caused me to be on the verge of vomitting on my way home. When I laid on the bed, it felt as though the whole world was spinning around me. Luckily my stomach was empty at that time so I didn't vomit. The whole feeling was totally awful. It was just for that night but I wonder why.
