I was taking 3 . One with my morning meds, one after dinner, and one before bedtime with my nighttime meds. I was also taking 1 womens multivitamin in the morning . Almost sounds like vitamin overload but not once while on that regimen did i have any hemoptysis....What a welcome relief !! BUT i ran out of ADEKS, and since i have to pay for them out of pocket ,i am back on my regular vitamin schedule, till i get more samples from my doctor.
