Modafinil is a wakefulness-promoting and focus-enhancing medication that is available only with a doctor's prescription. Modalert 200mg (modafinil) does this by assisting the brain in regulating its own sleep-wake cycle, which in turn reduces daytime drowsiness. You may take it with or without meals depending on your preference. Modvigil 200 (Modafinil) is recommended that you take it at the same time every day. Take the remaining tablets as advised, even if you are experiencing a higher level of alertness or energy than is typical for you. You should not abruptly stop taking the medications unless you are feeling withdrawal symptoms, since this might have serious consequences.
