You are having a really hard time of it @Erko_Girl_68 :( Hopefully someone who's been on Verzenio will jump on soon & help you with advice. Can the dose be lowered a bit til you stabilise?
Can you contact your Breast Care Nurse to chat with the Onc & hopefully get some sort of solution to your trots/clogged up issues?
When hubby had diarrhoea from his chemo, he took Gastrostop/Loperamide with each loose motion & was lucky not to get the opposite clogging as well. There must be something your Onc can do to limit those highs & lows :(
take care & all the best
