I am Little Lizard and I am a coffee-aholic.
I love the stuff and could not kick-start myself in the morning without it, gets me going a treat before a run or the gym. During a marathon I have a cuppa a couple of hours before then every hour into the race I take lemsip max capsules which contain caffeine along with paracetamol which seems to keep the cramps away.
Filter coffee is better than the powdered stuff as it contains more caffeine.
I limit myself to 3 big mugs a day, but if I had my own way, I'd slurp twice that amount. I also make sure I hydrate properly. Sorry, but I exercise loads, hydrate well and eat an extremely healthy diet full of fruit/veg/fibre/chicken/fish etc, don't smoke and drink once to twice a month, so deserve a little vice somewhere!
