Alcohol: maybe one drink per month. I generally don’t like the taste. Possibly due to me being a supertaster (https://en.m.wikipedia.org/wiki/Supertaster) as determined by a test kit I bought on Amazon due to having suspicions for a number of years.
Coffee: Again, I don’t like the taste, possibly again due to the supertaster factor (Coffee tastes way too bitter for me). I hardly ever drink coffee. I do, however, like mildly coffee-flavored ice cream, candy, or desserts sometimes. I usually drink water (not soda, and especially not caffeinated soda) with meals. Most of my caffeine intake comes via Sweet Thai Ice Tea which I usually order when eating at a Thai restaurant a couple of times a month. Also, perhaps once every two months I will order a sweet iced chai. Also, I generally can’t eat chocolate due to its theobromine being a migraine trigger for me.
Since, for the above reasons, I am exposed to caffeine so rarely, I tend to be lot more affected by it than other people are. One cup of something caffeinated can make my heart race and make it hard for me to concentrate.
You might want to do some reading of books about how to promote institutional change from within. If you can read, and then get your manager to read, "Creating a Software Engineering Culture" by Karl Wiegers, that might help. Also, "Refactoring" by Martin Fowler is highly advised.
Regardless, maintaining good relationships with your coworkers, and specifically your manager is key. One key insight I have gathered over the years is that whenever possible, there are benefits to avoiding telling someone "this is a problem/bad/whatever and needs to be fixed" if it is instead possible to say "That's great, and it would be even better if..." The criticism in the first form invokes a immediate defensive reaction once someone hears "this is a problem" which may cause them to not hear whatever you say next, and can create a teacher vs. student dynamic (see Pavlov's work on negative conditioning) in which they may actively start to resist your suggestions, while the second form is more likely to cause them to feel good at having been praised and want to seek further approval (positive conditioning, which tends to be much more effective and produce more long-lasting behavior changes in most circumstances). Some research on self-serving bias suggests that people are much more likely to believe what you are telling them if you can phrase it in a way such that it sounds like praise.
