Hi Kimmy and welcome,
Yes it can be very hard. But a month should be doable if you don't have a problem. After I started my drinking career in my 40's the thought never entered my mind to try to give it up for a month. I wish it had because I might have gotten some early answers. Instead it progressed to where I had to give it up forever. This happened in about 5 years, the past 2 or 3 years prior to stopping I don't think I had a whole weekend where I didn't drink alot. You will probably find more people who don't drink that you are just not aware of. Some nurse one or two drinks for a whole evening. You probably just didn't notice. Good luck and keep reading and posting.
