I believe many folks are sober curious because of concerns around their health, specifically their mental health.
The more the risks alcohol poses to the human body are written about, the clearer it becomes that abstaining from alcohol (for whatever period of time makes you feel best) is valuable.
The biggest uplift I felt when I stopped drinking was around my physical health. First, I remembered what I did the night before when I woke up (HUGE), my mouth wasn’t chronically dry, my hands stopped shaking (oh yeah I drank a lot), I didn’t smell like booze (yeah…a LOT) and I had energy to do stuff. I even bought a road bike to get around campus and loved going uphill (crazy, right?).
The most challenging aspect of getting sober was my mental health. The fact of the matter is, not drinking in our (American) culture is really – really – REALLY hard. It made me question everything about my life, my identity and how I was going to get through the next 10 minutes, every 10 minutes.
