Hi, I have had on going cronic headaches, frequent migraines, cronic sinus congestion, constipation, and occasional nausea. I am mostly vegetarian to help with hereditary cholesterol problems. I take medication for high blood pressure, vitamins, omega 3 oil and calcium. I have also been taking allergy drops, and have had several previous blood tests for underlying conditions or deficiency. I am always tired and generally feel lousy. I have basically tried everything to figure out what is wrong. Any suggestions?
