How did your doctor appointment go today? I've been thinking about you and hope all went well!
I, myself, had an icky day yesterday, especioally when I went home and I was kind of bad this morning, but it has let up since then.
Sometimes it's good to take the calcium at night before bed. That way it gives your guts overnite to settle and do its job. Maybe in the morning the D won't be so bad. I don't know though, I'm not on calcium. This is just what I've read on here. Do some experimenting.
Good luck! And please keep us posted.
