You're only human, Reluctantly. We can't think and research forever; yet I understand that big topics can seem oh-so-delicious. Try thinking of the topics that you think about as subjects in school. Show up 'in class,' learn, and then, after a set time, stop and move on to the rest of your day. Is this mode less free-form than, "OH LOOK KNOWLEDGE OMNOMNOMNOM!"? Yes, but it's also healthier and safer.
As for the Army, why not ask your parents to keep your things while you're on duty?
