What a difference a day makes. OK, a day and sleep.
So I got about 7 hours of sleep last night and I tried the Cavalier - Cognitive & Stress Support formula again this morning with no food and I was again back on track as far as focus goes. I popped the drug as I went to work at about 6AM on a completely empty stomach and I felt much more on task today and also much less irritable. I was also less paranoid than I typically am.
Today I was pretty alert the full time at work and still felt pretty good until about 5PM or so. (I got off at 2:45PM)
The effects started to wear off around 5:30 or 6PM. I'm encouraged and will continue to try it with water and no initial food in the morning - although I don't recommend you try this as there is likely a reason they recommend it is ingested along with food.
