Business
I regularly travel for work, often getting up at the crack of dawn to make a 9am meeting in a different country, or worse travelling on short over night flights that get you in on time but don't give you time to sleep. I've become immune to the "coffee" they serve on flights, and there is never time to stop for anything decent. For a while I used to buy a Red Bull on landing, but even stopping to do this was a pain, and I was always left feeling sick and bloated. Firestar has been a godsend, I keep a couple in my wallet, and take one before client and internal meetings. Almost immediately, I feel sharper more alert and more confident. I only wish I'd found it sooner.
