How so? Comparing relatively normal doses, the effects of caffeine seem subtle in comparison.
If you're a habitual user, you may not even realize how it effects you, and you'll need more dosage to get effects.
I'm a very long way from the folks on r/decaf, most of whom I think need some serious help, but it's much more impactful than you may realize.
Caffeine doesn't make me feel particularly great, and I feel almost no compulsion to have more than one cup, but it made him feel amazing, and he felt compelled to drink more.
I can stop drinking coffee for a week without any annoyance, but if he tries to pull back or stop drinking caffeine, he experiences 2 weeks of crippling headaches.
My takeaway: work your way into any drugs tentatively, and don't listen to people who tell you how much "everyone" responds to it.
I have to actively remind myself to consume my caffeine when I really need the boost in focus. The euphoria is a pleasing side effect, but not something I think about when I'm not experiencing it. It's common for me to go weeks at a time without having any, just because I didn't think to.
I think there could be a genetic factor here. Addiction (to alcohol, cigarettes, caffeine, etc.) seems to be fully absent in my family history.
I have an espresso superautomatic, beer in my fridge, and prescribed stimulants, and I often go months without partaking in any of that because it has to be a conscious decision and sometimes it never crosses my mind. I'm uncomfortable leaving my baseline.
It's like wearing fancy clothes. It's enjoyable for a few hours, but I wouldn't want to wear them frequently.
