Ativan Question!!!

I've been on Ativan .5mg for a little over 2 months now.

I started taking 2pills before I went to bed at night the 1st time I used them. (60 pill bottle)
After that bottle ran out in one month, I got a refill and my Dr. insisted I  just used 1 pill per night. (30 pill bottle)
That bottle ran out, and I got another refill.

Some nights I just take 1pill of 5mg... but some nights I take 2pills before bed.

My question is.

For only being on these for 2 months... will it be easy to get off them?
I dont want to rely on these for sleep. Is it possible for me to have really bad bad withdrawls for the short term I've been on them? Ive seen some youtube videos of people going through withdrawls and it looks TERRIBLE! But, I think they were LONG time users.

How long do you think withdrawls would last?
Thanks so much! =)

ps: if anyone would suggest a "tampering off" method for me that would be great too!
Thanks!

Well I guess I should say its called "Lorazepam" on my prescription bottle. But I think its generic for Ativan.
