Caffeine still works for me, at least in the AM, however a second boost of Sbucks at lunch only gives me the jitters, and while certainly awake,I sense myself being agitated, or short in attitude, probably not mentally pleasant to be around. (Some might say that is my normal state anyway, so Megan or someone else should offer the observations if my afternoons on a "push" of caffeine are real or my perception of how things are).

I would welcome finding an alternative that works. I too have seen the commercials, and now with reading this I am going to try it as well to see if it actually works. My hours at OCF are a far cry from an 8 hour day, more like 12-14, and I can't afford to just nap in the afternoon.

I don't know much about the downsides of B vitamins, and I thought they were water soluble so that ODing on them would be difficult, especially with those of us that drink tons of water all day long to deal with xerostomia. At one point in a doctors appointment, I revealed to them how much water I drink, as I am on the phone all the time with patients and more,and need it to talk let alone swallow, and the docs thought that it was actually detrimental to drink that much, as it flushed all the electrolytes out of my system. Clearly if this was true, I could drink one of those sports drinks to replace them, but chasing radiation induced caries all the time, I am reluctant to be rinsing my teeth in sugar water with regularity.

Anyone else who tries this stuff please post your impressions, I will also. If someone knows more about the B vitamin issue, I'd be interested in hearing it.
