Can I join the Marines with Adult ADHD?

I'm going to be a college graduate next year and have been thinking about joining the Marines after I graduate. I, of couse, am interested in becoming an Marine Corps Officer. I have been diagnosed with ADHD, but I am highly functioning and don't "have" to take my medication. I survived the first three years of college without it, but I like taking it because it does help me. I know that the Marines are stricter about medical waivers but is there any chance I can get a medical waiver? If I have amazing PFT and ASVAB scores and college degree with a good GPA and no history of drug abuse and am after a MOS that will keep me most likely out of the line of fire, is there any chance at all? Is there a MOS that would be good for me to choose? I'm in between Intelligence and Public Affairs. And if I do get a waiver, would I be allowed to take my medication during training? I also have tattoos, I have a heart behind my ear and rose vines down both sides of my back and rose vine on my left arm (easiest description). The one on my arm would show and behind my ear. I got them before I thought about joining the Marines, and they are not related to gangs or anything, and I work in childcare and I'm allowed to show my tattoos at work, so I think it's dumb I will need a tatt waiver, when I can show my VPK class my tatts and most military and my children's parents have tatts. Ok, sorry for any misspellings. Any advice? No dumb answers please -.-
