It is not your fault - he was supposed to weigh you and if he could not manage operating a scale, he could have at least sized you up visually! I cannot imagine that one can miss a 100-lb weight gain.

So do not make it your fault - it is entirely his fault.

I was on Zyprexa for a month, came back to my then p-doc who looked at my face and said "that's it, you are gaining weight, we are discontinuing the trial". After one month and probably (I do not have access to my chart now) 15-20 lbs up.

And I am still mad at her for even trying Zyprexa, even for those 15-20 lbs!

For 100+ lbs, I would vote to shoot him down, all his other good qualities regardless. So I am with Morethingswrong.
