Is honey good?
Honey is actually a better option than most sweeteners.
Is artificial sweetner unheathy or preformance inhibiting?
There are a ton of these out there, so it would depend on which ones. However, based on the limited research I've seen on it, stevia is your best bet as far as artificial sweeteners gp.
Is it better to sleep until you wake up naturally, to limit your sleep or to keep a particular schedule?
This kind of depends. If you're suffering from jet lag or you've got an irregular sleep schedule, it would be wise to regulate your sleep patterns. Once you get on a regular sleep schedule, you'll find that you don't always need an alarm because your body's biological clock will wake you up naturally.
Is food that rates high on the gi index ok to eat after you`re done playing or does it have lingering consequences?
In moderation, yes. Just know that you may feel a spike and crash, and plan accordingly
Is it better to do a light workout before playing and to save doing a more demanding workout for after a session or is working out before playing better? If working out pre-session is better, what should you do to recuperate from your workout before you play?
I wouldn't recommend working out IMMEDIATELY prior to playing, but aside from that, you're likely going to have to base this on body feel as it may differ on a case-by-case basis. To recuperate, I'd recommend getting a post-workout meal in and giving yourself a good 20 minutes prior to starting your session.
