I'll just consume it during an occasional weekend now or so and I'm definitely interested in trying some organic coffee.

I recommend good quality organic coffee and I am really against instant coffee or coffee beans that smell like ashtrays, they are coated in chemicals and instant coffee is like a laxative that leads to constipation in my opinion.

The whole thing I discovered when I used to drink coffee and tea a lot is that you build up a tolerance for caffeine so if you are drinking it regularly the effect eventually becomes roughly the same as not drinking it at all. And then you are just wasting coffee and becoming reliant on it for no reason and whenever you can't get it you'll get a crash and just feel tired and depressed as hell. If you simply don't drink it regularly you feel exactly the same and not have to worry about grabbing your cup of coffee in order to keep yourself awake. I know there's a little more to this and it's also individual but basically for me I felt getting good sleep is a more reliable energy source and exercise and time management helps give me that caffeine-like alertness when I need it but much better than caffeine could alone because it's focused. I've ultimately found caffeine extremely distracting, it gives me plenty of energy but it simultaneously ungrounds me making it harder to stay focused on the things I need to do.

Now, if you're drinking coffee all day and during performances that may be a different story. I should mention that my "cups" of coffee are 8 oz cups. Not the new standard of 16!
I also think that some of these so called issues may depend on what type of music one is singing. Someone singing classical or opera may want a more clear sound and everything counts. Someone singing more bluesy songs may actually benefit from a bit of alcohol or anything adding a certain amount of character to the voice
(without causing damage of course). It may all be situational and personal.

Consuming anything that may dry out the cords just prior to or during a performance may not be a good idea but imo as long as you are countering with hydration after, then I see no problems a few hours before actual singing. At least not for me. How many songs and what type you will sing makes a difference also.

What are your thoughts on this? Do you feel like it influences your singing personally?
