woke up early in the morning with sever blurring of the vision and difficulty inbalancing when walking had to hold onto walls for balance. following light breakfast started vomiting followed by dry heaves. the blurry vision and light headedness continued. by noon managed to hold down Dramamine. this relieved the symptoms some what. repeated Dramamine one more time during the day. next day (today) symptoms are very slight. I think it was some additive to the granola I ate the night before. was I right?
