starting accutane in a few days, very nervous!

hello fellow accutane friends,
I have sooo many questions and dont even know where to begin. I am 22 years old and a college student. I have had cystic acne since i was in high school and figured that once i was the age i am now it would be gone. Clearly its not and dermatologists have recommended accutane to me since I was 15. I have come so far as to say yes I would try it but chickened out at the last mintue.
Finally, I have given up, I have literally tried every single antibiotic and cream there is and althought my acne isnt that bad it is rediculous. I have it mainly on my chin and back. I am beginning June 7 and am so nervous and have so many questions.
Hopefully you guys can appease my mind and convince me that taking accutane will change my life for the better, it will be worth it in the end, right?
1. I will be in the sun a lot but do not burn normally very easily as I have olive skin due to my mediterranean roots. Will the sun be a huge issue, can I even lay outside?
2. Is the usual time span 4-6 months to be on the drug or does it depend on how bad your skin is?
3. Are second rounds of the drug determined by how bad your skin is to begin with or does that not make a difference at all.
4. Obviously I drink alcohol, I am in college. I don't need to drink a lot but when i do drink, do I just not take my pill that day or should I just watch how much I drink.
5. Does your hair fall out or become thinner? I feel like thats just a rumor but I don't know
6. Ok so the "big breakout" as ppl call it, I read that occurs in the first few weeks/month that you're on it. Just how bad is this break out, like is it just like you'd get a typical bad break out or is it like worse than your worst break out? I am very scared for this

Ok thats it for now, I say that as if I wrote a sentence. Sorry but I tend to be a worrier and it took me years to finally go on this drug and I'm actually doing it, I want my life to change and I think this will help me gain my confidence back. Please respond soon and thanks in advance!
