I've been going to al-anon and ACoA meetings and I really find that they help deal with IC  just as much as alcoholism. The serenity prayer may seem hackneyed since we've all heard it so often but it helps me woith this disease and this treatment.

God, grant me the serenity to accept the things I cannot change

the courage to change the things I can

and the wisdom to know the difference.

I say this out loud when the panic of "when? Why?" starts up.
