Yes you are right that meibomian gland disease (MGD) is a major cause of dry eyes. If you do have a combination of MGD and dry eyes, there are many ways to treat them! However, since you mentioned that your eyes are neither dry nor painful without contact lens use, I suspect you may have another condition known as Giant Papillary Conjunctivitis (GPC).

There is a cumulative therapeutic dose in the range of 120mg – 140mg/kg that some doctors adhere to in the bid to reduce the relapse of acne. Sometimes, doctors may prescribe lower doses (with lower side effects) until the acne has cleared and continue the course for a few more months after. It really depends on the prescribing doctor as each has his/her own protocol. If you find that you are still having relapses with lower doses then discuss with your doctor the option of a course to achieve the therapeutic accumulative dose.
