It was a real trial-and-error type of situation. The first call to our attention was the caffeine and how it would build up in my system. After that, it became a matter of watching carefully what I ate, what medicines I used - basically evaluating what I put into my system and how it would affect me. It was a lot of journaling so that I could remember clearly what was going on at each instance and convey it properly. It's now Day 3, and I am feeling much more like I prefer and should feel rather than the lower level of functionality of the end of last week.
