Promise to tell the whole truth, the full truth, and nothing but the truth.
I find its helpful for me to be honest by keeping a little notebook of the things I do
and when I do them and then basically just read it when I'm asked by my doc what's
going on. Maybe you could even print off your entries from here and just hand them over.
Then there is no way to lie.
In the end, the lying only hurts you. You can only be helped as much as you're willing
to be open.
