I'm guessing you are fairly young (and healthy). There are medications that can cause the problem. Anemia is another one. That would be more likely in a vegetarian. If neither of these apply, it could be as simple as not drinking enough water during the day. Dehydration can affect blood volume which can lead to OH.
