is a time-released
version of the drug Methylphenidate
, which is also known as Ritalin
, and is used to treat depression
, and Narcolepsy
. It comes in capsules which contain 18,36, or 54 milligrams of Methylphenidate
which is slowly released over a period of 8 to 10 hours. Its main benefit over Ritalin
is that it only needs to be taken once a day, but it is more expensive than Ritalin
, or its generic
equivalent. It also means that once you take it, it will be difficult to get any sleep until it wears off in about 12 hours. This can be a benefit or a curse, depending on your need for sleep. Amphetamines
are not a subsitute for proper sleep.
