Caffeine Addition: Progress Report

On 20th September, I made a post titled Caffeine Addiction in which I discussed my then very recent withdrawal from tea and coffee and their replacement with warm water and nothing else. I'm happy to report that for nearly two months I was able to maintain my "sobriety". Apart from an occasional fruit juice and one cup of hibiscus tea, water has been all I've imbibed.

Today however, I was "forced" into drinking a small cup of Americano at a restaurant. The reason for doing so has to do with my sleeping pattern. Over the past weeks, I'd fallen into the habit of sleeping around 9am, waking up in the afternoon and then snoozing again some time in the evening. Overall I was still getting seven to eight hours of sleep but divided into two quite separate parts. 

Circumstances conspired so that today I was still awake at midday having foregone my morning nap. Together with my family, I was in a restaurant and found myself in a severe sleep-deprived state. In order to keep functioning, I ordered an Americano to accompany my meal. The potency of its effect really surprised me. I was instantly alert and able to function more or less as I could have with my morning sleep behind. Furthermore, I was able to remain awake until almost 10pm of that same day.

For the first few hours after the drink, I was quite "high" and come down slowly over the remaining hours. I was reminded yet again of how potent coffee really is. I don't intend to return to my caffeine-drinking days and am happy to maintain my water only liquid intake. Upon waking up at 1am of the next day (having slept for about three hours), I noticed that I had drooled a little onto my pillowslip and that the smell of the saliva had the same slightly unpleasant smell that it used to have in my coffee and tea drinking days.

Since drinking only water, I drool less and when I do, it has a neutral odour. Presumably the caffeine is being excreted via my saliva when I sleep. Overall my health is good. I've managed to go for a brisk, twenty minute morning walk on most days combined with some light exercises throughout the rest of the day. My weight remains constant at around 71.5 kilograms. My thymoma has not been causing me any significant problems. Lying here, typing this blog post, my resting place rate is about 65 which is "good" (see Figure 1).
