Provigil is sometimes prescribed to those who are obese in order to help deal with the chronic fatigue often felt by people who are severely overweight which is caused by not only carrying around all that weight but also the sleep apnea that many obese people suffer.
Provigil has side effects, as do all medications, and it is important to be aware of them. Provigil has been known to cause dizziness, vision difficulties, and headaches. It may also affect the body’s heat control system resulting in excessive sweating and, due to the lost fluid, excessive thirst. Those taking Provigil may also experience an uncontrollable shaking of a part of the body. As with all medications that affect sleep patterns, Provigil may result in the experience opposite of that for which the user is looking, putting to sleep those who are looking to stay awake and vice versa.
