I'd like to say some more about taking refreshments before sitting to meditate:
Guidelines are just that - the general rule for everyone, but there are always justifications to get around the rules.
If you are going to be sitting for 10 minutes in meditation than an hour fast before sitting will probably not make you uncomfortable, since the total time of abstinence would be one hour and ten minutes.
If you are doing an hour meditation, after the first few minutes the regular meditator will lose body consciousness, and so the point becomes mute.
Strive to comply with the guidelines, and if it takes time, so be it.
Daily, new people are reading this thread, so I will continue to remind about abstaining from refreshments for an hour before meditation.
Do your best and don't worry about what others are doing - as Lisa says just above, we are all different.
