<human>: My 21st birthday is coming up in a few months. I'm in college in the US, so turning 21 is relevant because it's the first time a person can legally drink. My friends are trying to be good friends and are planning on taking me out to a bunch of bars for my 21st birthday. 

Like most people my age, I've already been drinking for a number of years before now, just not legally. I've never liked it, and I never drink to excess (sticking to around a drink or two an hour). I just really don't enjoy the feeling, taste, or the way it affects me afterwards. On top of that, there is a huge history of alcoholism in my family so I that deters me from drinking more as well. 

My friends know these things and we've drank together before and I stick to my rule of not really drinking much. However, they keep talking about how they are going to take me out and get me blackout drunk. I've repeatedly told them I don't want to do that, albeit not especially firmly. 

They are just trying to be good friends, but I don't think they see that what they would want is not necessarily what I want. How do I tell them that I won't go out and get alcohol poisoning with them?

Could you distill the essence of the text into 1-3 sentences?
<bot>: Friends are trying to peer pressure me into get wasted for my birthday, I'm not sure how to turn them down.
