Modafinil (US trade name Provigil, with a levorotary-pure form Nuvigil) is a fairly ānewā drug in the class of eugeroics. In my experience, Modafinil does exactly all the therapeutic things for daytime sleepiness and focus that methylphenidate (US trade name Ritalin) does, but a little better, but without the fun stuff like a rush, or the letdown side-effects (suicide tuesday is a real thing for people who love traditional stimulantsā¦ Like me.)
I switched and itās greatā¦ I wish I could get that rush ritalin had, but if weāre being serious adults and treating psychiatric and physical stuff, Modafinil is a great drug. Works on the same stuff in the brain as Ritalin, but starts earlier in the chain so itās less reinforcing and less addictive.
When I would go a day without ritalin Iād get sweaty and fiend for it and start looking for other sources of classical stimulants just to get my fix. When I miss a day of Modafinil itās more like my brain is just slower than normal and Iām dumber than I usually am. Not so much withdrawal as Iām running on lower grade gas. At least I donāt get headaches and feel like Iāve run a marathon when I miss a day of it.
And thereās a legal, unregulated prodrug for Modafinil widely available in the US called Adrafinil. You have to deal with purity issues and the standard bullshit from chem suppliers, but it generally works. Itās harder on your liver though. And while Iāve never tried it, a friend has, and they get sleepy when they take Adrafinil, so, YMMV. They havenāt compared it with Modafinil because the real prescription stuff is so expensive. At my local pharmacy without insurance 30x200mg tablets costs $3000 even though itās been out of patent for years now. Itās just that thereās only one company that makes it, and theyāre not sharing how, even though patent filings BY LAW need to be good enough for an average pharmaceuticals chemist to synthesize the drug just using the patent.
Blah blah, patent is broken in the US, my standard spiel etc.
ETA: For me, a dose of Modafinil has a therapeutic effect for about 6 hours. YMMV of course, but I had to get a script for ritalin on top of it, because I work an 8 hour shift and have a 1-2 hour drive home depending on whether thereās a sportsball game in town. The Modafinil wears off about two hours before my shift ends, and my performance goes down the toilet. And a 10mg tablet of ritalin works for about 5 hours for me, so I take it about 3 hours before end of shift, get a burst of work done, make a ton of calls, and drive home like a madman. I have a lot of blood with my >40 BMI so it doesnāt really affect my ability to go to bed. Thatās what the BBS is for. I hang out here till itās way past when I should go to bed, then I crash.
ETAA:
The term āEugeroicā means: wakefulness promoting agent. And thatās really the best way to describe the effects of Modafinil. It doesnāt wire you up the way stimulants do. It makes you, almost miraculously not tired. Like I can have my alarm go off four hours before my normal wakeup time, take my Modafinil, go sit in a chair and doze for half an hour, and when it kicks in, Iām as awake as I am at lunch time, but Iām not jittery or speeded up. Just suddenly awake and ready to do whatever, like Iāve had a good nightās sleep.
