I will get a dizzy lightt headed feeling every several days, I have been given meclazine to take every morning and then as needed. This morning I did not eat until lunch and felt bad, but not as bad as a dizzy attack. I have been checked for BP, Blood Sugar, MRI on brain, and with my cardiologist. My next appt. is with an ENT. Nothing seems to reveal the cause. Can you tell me another thing to check?
