Might seem that way but the contempt won't last forever. It is a very difficult process you are in the middle of. Takes time.

For me I was giving up my best friend, alcohol. Once I was ready to give it up for good I still had to grieve it. I still had to get really pissed about why others could drink normally and I couldn't.

Best not to think about the whole future. That's why we do it one day at a time. Go your 100 days and see how you feel then. In the mean time don't think about it as the rest of your life. Alcohol and all the others will always be there.
