>Sometimes I'll just grab a 300mg energy drink at the store or take a couple Excedrin on an empty stomach if that's all I got.

Not suggesting medication or that you take something you shouldn't; absolutely do your own research!

Look into HVMN Sprint. Pretty long shelf-life, well-controlled dosage and focused on focus rather just ENERGY TO THE MAX.

I loved Monster back in the day but its taste makes me sick just thinking about it.
