At this point I have all the information I think I am going to get to determine whether coffee is something I will be doing in the future. The results are in 2 major categories, sleep and bathroom stuff. I am going to be as tasteful as I can, but if the scatological bothers you in any way, don't read further.
- Sleep: Within 4 days of stopping decaf in the morning I slept better than I had in years. I woke up at night hardly at all and woke up feeling refreshed much more often than not. In the recent, coffee drinking past, I awoke each night once or twice. When I added a single cup of caffeinated coffee I sleep very poorly for 2 nights in a row. When I added a single cup of decaf I slept worse than with no coffee, but better than if it was fully caffeinated.
- Number 2: While not perfect, bathroom cleanliness improved also within about a week of stopping coffee. This was not consistent, but the baseline, so to speak, was better overall. Things were a bit drier and more well formed, requiring less clean up afterward. I can't believe I am writing this. Once I added the single cup of decaf back things reverted to the wetter, messier state fairly quickly and cleared up after a couple of days dropping the coffee. Different foods I eat, nuts particularly, tend to make things even worse, but I could only tell that once I removed the baseline problem causer of the coffee. I am not sure if it is the caffeine or other substances in the coffee, but either way the problem is worse with it. It is a bean, after all.
My overall conclusion is that drinking coffee on a daily basis is a mistake for me. Even decaf in small doses daily bothers my sleep and bathroom situation enough to not make it worth it. As a result, I will be almost entirely coffee free in the coming future. I may have a cup of espresso or dry cappuccino from time to time as a treat in small doses when I know I will have the opportunity to sleep in. I may not even do that.
The hardest part is Sunday morning(now), when I used to have 2-3 cappuccinos while we lounge around and relax. I enjoyed the taste and miss it.
