Hi HumanAction,
You've described a number of different things, and have asked some important questions, so I'm going to break all of this down in the order that you presented the information.
1) Considering the lack of sleep, minimal preparation and pacing issues, the 490 is not so bad (the average GMAT score is right around 540-550 most years). That all having been said, you have a lot of work to do if your goal is to push this score into the 650+ territory.
2) Is your ADD documented? If you received any type of "accommodations" for testing (during school or under other circumstances), then you might be able to qualify for testing accommodations on the GMAT. Even if you've never been formally diagnosed, you might still be able to get a prescription for it now, which could help with your studies.
3) Since you don't have a fixed "deadline" to take the GMAT or apply to Business School, you have the freedom to plan for a longer study period, which could greatly increase your chances to score at a high level. Assuming that you'd like to apply to Business School sometime "soon", you could start studying now and retake the GMAT before Round 1 deadlines. Even with a much longer study period, you could still make the Round 2 deadlines. If your current score is enough for your MS program, and you'd rather focus on that, then we need to define what that schooling involves and whether you want to ALSO go for an MBA later.
4) You're not likely to hit 650+ in 31 days. Most Test Takers need 3 months (or more) to hit their respective "peak" scores. While you could certainly score higher than 490 in 31 days, a much larger score will require a greater investment of time, money and effort.
Your background may or may not throw up some 'red flags' at Schools, but you could conceivably "theme" your application around the ideas that you've taken control of your life, joined the military, become more responsible, etc. THAT type of story will help you to 'stand out' when you apply. Depending on your eventual GMAT score, you might want to work with an Admissions Expert to properly present all of these ideas.
GMAT assassins aren't born, they're made,
