Every weekend I pomise myself I won't touch vodka RedBulls. After I get to pint 6 or 7 though I go off beer and vodka RedBulls go down so easily I end up on em again.
I remember one night I'd worked a long shift and had been up for 20 hours before going out with a mate for his birthday. I felt shattered so took some ProPLus to try and keep awake. It didn't seem to do anything so I drank red bull all night. I still remember the horrible feeling of lying on my bed at 6:00am the following morning feeling so physically tired but my brain was buzzin and I just couldn't settle. Never touched ProPlus since and it took a long time before I ventured onto the RB's again
