This is my 5th day on 150mg of Nuvigil. I really havent experienced wakefulness yet. Im still very tired, all day. I tried to not take caffeine but since i have to work i have to have some sort of caffeine to stay awake. The first 2 days of taking it i didnt have caffeine, and i took it on an empty stomach. waited an hour to eat. Ive taken it at different times to see if that would help, pretty early id say. 9am or 10am, and by around 5-7 im a little more awake but not enough to lay down and NOT sleep. I would still be very tired. I suffer from constipation so i dont know if that could be the problem or it will just take longer for me to notice anything? And if so how long? Im still wondering if i should ask my doctor to up it to 250mg
Talk to your dr, It should have worked almost the first day. Are you sleeping at night, quality sleep? How long?
Nuvigil should promote wakefulness within the first dose or two. The general max is 225mg, but I have been prescribed as much as 300mgs for hypersomnia. I, too, had a sleep study done with no result of apnea. I believe my problem is from the other medications I take, but there are numerous other reasons you maybe tired besides apnea. Have you had a complete blood work up?
I was prescribed Nuvigil for POTS, postural orthostatic Tachycardia syndrome which causes excessive daytime sleepiness. That may be something you want to get tested for it you already have been testing negative for all the other tests. I got a sleep study done w the whole works and it came up negative, my blood was negative and I had no good reason to understand why I was so sleepy. If you want to get tested for POTS go to a neurologist, preferably one from disautonomia internationals website. Best of luck :)
