Will taking Modafinil affect my ability to fall asleep at night or interrupt my sleep?

synapseProvigil has a 15-hour half life (the amount of time before half of the drug's peak plasma levels are eliminated by the body), meaning that if you take a single pill in the morning the drug will probably have little effect on your night-time sleep.

Remember: your body and brain need sleep! Provigil can be abused, like any drug, and if you take it too often you could not get enough sleep. Stay within the recommended dosages and get regular sleep.

Can I become addicted to Modafinil?

Modafinil is a Schedule IV controlled substance. This means that Modafinil may be a target for people who abuse medicines or street drugs. However, certain chemical properties of modafinil, the active ingredient in Provigil, reduce its potential for abuse. Because the drug is insoluble in water, it cannot be readily injected. Also, it degrades with heating, which severally hampers its effectiveness if smoked. There has been some finding that modafinil affects dopamine in the brain, which raises a flag that it might be addictive.
