I agree with D122y. Just be honest, that's a big part of sobriety - not bowing to others when it is out of step with my own health and serenity.
There is a great section here, the Friends and Family section, and there are a lot of sticky threads at the top of that forum. Boundaries with others is a big part of healthy life.
