As you already might know Provigil

Is a drug aimed to help people to increase wakefulness and minimize the effects of such sleep disorders as narcolepsy, obstructive sleep apnea and other caused by working late night shifts.

Provigil comes in tablets of different doze. First of them contain 100mg only and aren’t that effective as the second kind however the chance to get any side effects is lower as well. The second type is Provigil 200mg which will give you much stronger effect however you risk to get some kind of side effect as well. Anyway, you don’t risk anything if you consult your doctor or pharmacist before taking the drug. Even if you are allergic to some components of the drug nothing really terrible will happen. Most side effects of Provigil and similar drugs are light headache, anxiety, dry mouth, rapid heartbeat, high blood pressure and other effects of that kind. The same thing happens if you drink energy drinks while you aren’t supposed to, especially if you drink too much, right? So, ask yourself if you are risking that much taking that medication. Also you should think about the effects that you are expecting of taking the drug. To draw a conclusion you need to compare possibility of suffering from side effects of some kind against the deserved results. If deserved effects outweigh the shortcomings then keep on reading.
