I've been taking 200mg day for 7 days spread out over 4 weeks now. Netdaypets is day 8. I've noticed that on nights after I take it, I don't really get a good nights sleep. For some reason I feel like I'm half awake most of the night until early morning. I'm having dreams so I know I'm getting some rem sleep, but it's not as restful as on days I don't take modafinil. I take 1 200mg around 7-8am and go to bed around 10pm so it should be metabolized and clear of my system by 10pm. What's wierd too is that on nights I smoke, I sleep normally even if I've taken modafinil. Anyone else experience something similar?
