Hey there, welcome to the forum!
From what I understand, you took xanax every night for 2 years, you CANNOT go cold turkey on them. Benzos need to be tapered off very slowly.
I used to take oxazepam, which is kinda like xanax, a short active benzo as well, 200mg/day for 9 years, it took me 14 months to taper it off and it was not a walk in the park but it was soooooo worth it....
Can you give me more info on how much you are taking, why and why you wanna stop? I don't mean to be intrusive but it'll help me to help you.
avisg gave you the site already where to find A LO of information, here's an example of a taper plan from xanax: http://www.benzo.org.uk/manual/bzsched.htm#s1
