I just started adrafinil this morning. I started with 300 mg, didn't feel a very noticeable effect, so I took another 300 mg a little over an hour later.
I became extremely drowsy within an hour of taking the second dose. I didn't feel sedated or mentally impaired, but I just felt the profound need to lay down and close my eyes. I ended up taking a three hour nap only a couple hours after I'd woken up from 9 hours in bed.
To make this matter even weirder, I've been a hardcore insomniac for years and I rarely sleep more than a consecutive hour at night. Being able to easily fall asleep like that is very notable to me, and it's so bizarre that it happened right after I took a drug that's meant to counteract narcolepsy of all things.
I took the adrafinil with a 12 oz cup of coffee. I'm also taking a stack of noopept, aniracetam, piracetam, and phenibut(which never makes me drowsy). I was also on a low dose of sida cordifolia and panax ginseng, both of which are so mild that I didn't worry about mixing them with another stimulant. I take sida for its liver regenerating effect and ginseng for its antioxidant and immune boosting properties, not for their fairly negligible stimulant effects. None of this should've interacted with the adrafinil as far as I can tell, aside from maybe the phenibut. But wiki says that modafinil may work via "inhibiting GABAergic neurotransmission", so if anything wouldn't that mean that it would make phenibut LESS effective?
I'm also in the process of recovering from a ridiculously severe pulled muscle I got from excessive exercise, so maybe the drowsiness is just due to my body trying to recuperate and has nothing to do with the drug.
Has anyone else here had this strange reaction to adafrinil?
