Read faster but I didn’t notice any such benefit but I coincidentally had gone to donate blood in about the third week where they always check your blood pressure and discovered my BP was jacked up so I immediately stopped that experiment. I think that drug is widely over prescribed & can not be healthy for long term use. It just seems like an upper or stimulant is bound to put stress on your heart. That may be fine if you’re a kid but longer term... hmm!

Caveat: I’m not a doctor!
