Unfortunately, when it wears off, you are back to square one because the body eliminates it fairly quickly. It does not have a cumulative effect. But that is the reason why it may work better to split your dose and take more often so that you always have a dose going in and coming out. Most of the time the doctors prescribe 60 mg three times a day to start, but you will find that you have to find what schedule works for you because every individual handles it differently.

My body absorbs just about any drug I take fairly rapidly, then I get all the results at once and am left symptomatic until the next dose. This is just a suggestion and may not work for you, but is worth a try as long as you don't exceed the daily dose your doctor has prescribed.
