Lisa p -- I too no longer drink and I know exactly what you mean about being the first person ready to leave. It's not that I don't enjoy socializing without drinking but I can't just spend hours doing it the way I used to.
As for my own healthy habits, I am trying not to eat what I think of as obvious sugar and fat laden items. I'm not really cutting out sugar--just not eating things like cookies, candy, ice cream etc. I've been doing pretty well with this although I seem to have become addicted to Lara Bars as a somewhat "healthier" alternative. I've been a vegetarian for almost 30 years--my diet, apart from that is reasonably good.
I run almost every day but the class that I used to take that incorporated weights seems to have ceased. I have trouble motivating myself to do weights at home--need to look into finding a new class. I would love to try a Yoga class and may look into that for the new year. I have several friends who have done yoga for many years who I think could recommend a good teacher.
