I Am Told By The Doctor To Take One Orange

I am told by the doctor to take one orange tablet before breakfast in the morning. Two identical tabletsin the afternoon after meal and the biggest tablet at night after dinner. Though I take these tablets like that only, I many times don't follow the exact timing. Like sometimes I take morning capsule at 5.30 or 6.00am and sometimes I take at around 8 or 9 am. Like that in the afternoon and night 1-2 hrs difference happens. Is this OK? I am diagnosed with pulmonary coch's.
