Ahh Buckfast, I love to hate that stuff.
You're description is on the money Ewen. When I sit up to watch the UFC I always get a bottle of 'tonic' and stick it in the fridge for the 3 o'clock rumble. I crack it open at 3 on the botton and drink it while enjoying the fights. By the time it's over (normally around 5.30) I'm ready for bed. I always wake up before 10 though, absolutely WIRED.
I use it as a tool really. When I'm earlyshift on the Monday it would be difficult for me to get to sleep on the Sunday night if I had sat up for the fight on Saturday, due to sleeping half the Sunday away. With the tonic I'm up for 10 and shattered by 8. Spot on
As a side-note. I managed to convince my Wife to drink a bottle once she hit her target weight, it was a deal we made after she used the excuse of her diet for not having any. She was absolutely blitzed before the bottle was done and loved the effect of it, although she really hated the taste. A few weeks later her friend was up visiting so we all decided to get a bottle for a laugh. This was a little snippet of what happened after they were finished...
