I have a bunch of a questions involving sex, booze, anti-depressants, and adderall

OK my situation is pretty strange...

(BTW I'm new here and the whole using "SWIM" and "SWIY" is rather annoying for me so I'll just use the good old fashioned first person pronouns)

I have two major problems... One is that I'm almost positive I have ADHD. I have a doctor's appointment coming up and I plan on telling them that I have an extremely hard time concentrating/staying still/etc.. I really need it.

My other main problem is that I have pretty bad premature ejaculation... Completely sober I might last thirty seconds with a blowjob or sex. Yeah. It completely sucks and it really limits me... especially in college. Because of this setback, I told a psychiatrist a few months ago I was depressed so I could get some SSRIs to combat my premature ejaculation. It wasn't a complete lie because I was pretty messed up over a break up with my ex, but I didn't believe I really had depression. I took the meds (Paroxetine, 10 mg) daily for about 3 weeks and then had sex after having about 11 shots of vodka/captain morgan. I had some trouble getting hard, and then I still came too early. I got angry and stopped taking the meds.

Now last week, I decided that perhaps 10 mg was just not enough for a person of my size. I popped three of them (so 30 mg of generic paxil) and then had about 4 shots of vodka. I then hooked up with a girl. I didn't have any trouble getting hard and then realized that I lasted SO much longer.

Now here are my questions.

1.) What's the best explanation for that phenomenom? Is it that I took SOME booze and not too much? Is it because I took more SSRIs? Or is it probably both? I'm seriously not sure what was the thing that really helped. I barely felt buzzed by the time I had sex the second time, but maybe I drank just enough?
2.) I'm aware of the dangers of using SSRIs with alcohol, but not so much about adderall with alcohol. I've read that adderall actually decreases the effects of alcohol while ssris amplify them. What happens if I take anti-depressents, adderall, AND alcohol?
3.) Will adderall by itself help my premature ejaculation?

I'll probably have more questions later.... Thanks in advance!
