If you want to be productive all day, I recommend you use ammonium inhalants. Good news! It also works even when you have a hang over from last night drinking.
I've tried this drug to keep me awake when I feel sleepy and there are still lots of things I should do. Plus, unlike marijuana, it's legal and is much safer to use with little to no
side effects. If you are wondering how this drug works, it simply dilate your blood vessels allowing you to consume more oxygen thus making you more alert and productive.
You can use the liquid or the solid ammonium inhalants. Just be careful not to use it everyday as like other drugs, too much of everything is bad.
