Apparently the reason Rangers’ heavy hitter Josh Hamilton was out for “vision problems” was excessive caffeine intake (emphasis mine):
Hamilton, 31, said he plans to back off the caffeine, which included chocolate after games and an energy drink before games — not to mention what he was consuming all day long.
When it isn’t crack, heroin, or booze, it’s caffeine. Hey, at least this substance isn’t regulated or outlawed. It seems Josh’s personality is the type that tends towards any kind of addiction to the point of self harm.
