Another bonus to meth is that it helps you make all the right choices with a clear focused mind.
Day after day.
I do however recommend that you allow yourself to crash and burn at least every 30 days or so.
I've read that the body needs at least 8 hours of rest per month to operate at full capacity.
IMO I recommend staying away from Red Bull. That stuff will damage your organs and eventually kill you.
Not to mention that it taste like crap.
