I remember very clearly that you asked your pdoc to increase the Aplenzin because you didn't think it was working as well anymore. Taking the higher dose may help with the increased anxiety, jumpiness, and feelings of being out of control you are experiencing now. You sound very uncomfortable. Could you talk to, or email, your pdoc about it?

I'm sorry that you feel like you need to cancel your lunch date with Zeynep. I hope that you can reschedule it. I know that you enjoy talking with her, and it would be good for you to get out...
I'm sorry that you don't feel well today (((HUGS)))

You can try taking 100mg of Colace at night along with the Lactulose you are taking if you feel like you need to soften your stools to make them easier to pass. I was on Lactulose many years ago, and that's what I would do.
Have suppositories helped you in the past? They never worked for me.
