I STARTED TAKING AZITHROMYCIN YESTERDAY FOR A SINUS INFECTION. AFTER THE FISRT DOSE I BEGAN TO FEEL GROGGY. IT WAS DIFFICULT TO DRIVE AND I WAS VERY TIRED AT WORK. I SLEPT WEEL LAST NIGHT AND TOOK MY MEDS THIS MORNING BEFORE WORK, AGAIN I BEGAN TO FEEL VERY GROGGY. I WAS FALLING ASLEEP AT THE WHEEL. WHEN I GOT TO WORK, I FELT VERY TIRED AND OUT OF IT. I HAVE TAKEN ANTIBIOTICS IN THE PAST AND I AM SURE I HAVE TAKEN THIS ONE AND NOTHING LIKE THIS HVAE EVER HAPPENED. IS THE FORMULA DIFFERENT. I HAVE TYPE II DIABETES AND HIGH BLOOD PRESSURE. IS IT POSSIBLE THAT THE ANTIBIOTIC INTERFERRED WITH THOSE MEDS?
