i have ADHD tendencies.. but are they enough to classify me as having ADHD?

i dont even know if that's how it works, but the tendencies i DO have BIG TIME are:
binge behaviours.
it's hard for me to control my binge eating for example...
and most other things i enjoy, i always end up overdoing it.
i could never ever in my life be just satisfied with a single bottle of coke/pepsi.

as soon as i take the first sip, i know i'm gonna be drinking 4 liters that day.
yes, 4 liters.
and that's despite it affecting my health worse than it affects most people's health...

(i have a condition which requires me to get great sleep, otherwise i'm really fucked up the next day) and obviously it's full of caffeine.

so i choose the dopamine release from the junk foods, over my health.

i heard from soem ADHD people that caffeine doesn't affect them -- that's definetely not the case for me, it affects me big time.

and hmm, what else? ... it's hard for me to keep a hobby for longer than a month or so.

there's so many things i, by now, could have been extremely talented at, if i just kept going with it, but i always lose interest.

there's also other personality traits i can't really put my finger on right now,
but i know that for a fact, because one of my best friends has big time ADHD,
and we share a lot of personality traits.
