Do you drink water regularly?
These could be symptoms of dehydration. Try slowing sipping water for the night/day, stay away from salty things, alcohol, drugs, extreme physical activity, anything that will continue to dehydrate you. When we become dehydrated our nervous system doesn't communicate with the rest of our body correctly and will "fire" signals to our muscles to move involuntarily. This also causes dizziness, the brain needs more nutrients than any other organ in our body this includes water.
However, you should see a doctor if symptoms last longer than 24 hrs.
