On fasting

So, for various reasons, I thought it would be a good idea to spend Thursday fasting. I did, and it was alright, but, I noticed these things:

• Not eating isn't hard. Being sharp while in meetings a little difficult. To combat this, I drank non-caloried coffee. It helped BUT
• Not eating all day and having coffee at 3:00 pm (which I usually do with no problem) kept me unable to sleep until almost 2:00am. Not good for a working day. AND
• Friday, the day after, still feeling dingy. AND
• On my Saturday fast last weekend, I actually worked out for a couple of hours early in the day and worked out hard the day after. These seem to have worked well with the fast. Being at work, I was not able to do that. 

So, next fast will be next SATURDAY. I think I'll keep that a weekend thing.
