preserving vocals?

Well I tried diluted lime juice today. It seemingly added 2 hours to his voices lifespan. I'll report if honey does any better and if I try lime juice again maybe we can see if it actually helps or if today was just a fluke.
 
haha i remember in my session...
my vocal smoked pot and his voice got more open and heavier..
Weed is a must for me


Out of curiosity, what happens if the vocalist doesn't smoke weed. Or he passes out after half a joint, wat do then?

I remember tracking vocals for my bands old EP, vocalist was brilliant and could go for hours (thanks to the aforementioned zen of screaming dvd), but the second he came in after a cheeky joint, his voice crapped out and sounded shit compared to previous takes.
Therefore, I am calling bullshit.
