A number of drugs are very good in controlling symptoms. In addition to more recent therapies that focus on sleep-wake regulation, doctors frequently prescribe wakefulness-promoting drugs like modafinil or armodafinil. One kind of modafinil that is frequently used to lessen excessive daytime drowsiness and increase alertness is Modvigil 200. Medication is often most effective when used in conjunction with frequent medical follow-up and healthy sleep practices.
