A coworker of mine is leaving for boot camp in June. He was telling me he's trying to wean himself off coffee and cigarettes before then. Now, barring any judgment on the actual addictions and obvious health implications, what were your/your SO's experiences with this? I didn't think they forbade either, though I have zero personal experience with boot camp. I guess it doesn't matter either way, but now I'm curious. Do you think he "has to" give up either?
