DISCLAIMER: I am not a physician of any sort- I am however, a person with **severe** ADHD. I tried Modafinil when the Adder*ll shortage began and I’m now a monthly customer. (I have never taken my ADHD prescribed medication along with Modafinil because I’m not trying to go into cardiac arrest- I only take it on days when I want a break from my RxAdder*ll. When taking it I feel focused, my thoughts have more clarity, and I don’t have the awful crash I experience from my Rx. Normally, with stimulant-esque pills/tablets taken, food sounds/is repulsive because the meds have decreased my appetite so much. What I like about Modafinil is, I actually have an appetite while remaining focused and self motivated (another HUGE difference). The only reason I gave 4 stars is because shipping takes a month I stg. It may say 2 week shipping when you’re checking out- but that’s AFTER everything goes through customs (which takes weeks). All in all, I strongly recommend!!
