Provigil has become so expensive it is nearly impossible to consider using it regularly for the relief needed. Modalert has been developed and sold by Sun Pharmaceuticals as an affordable option. It comes in both 100 mg and 200 mg tablets. Originally, the drug was developed in France and approved for use to treat narcolepsy in 1986. It is a derivative of the medication adrafinil. It is less commonly used now than its generic counterparts. You can buy Modalert online with ease from our online store.
