From Gackt's latest blog:

"僕に関して言えば､
覚えているだけで二〇〇杯以上ショットを飲み干し､"

As in :

"As for me,
I only remember drinking around 200 shots "

lets see (dee use to work as a bartender :D)....

a shot of tequila is 50ml

50ml x 200 shots = 10000 ml

10000 ml = 10 l

10 l of tequila GACKT???? In one night??? really?? read my lips:

AS IF!
