Some people will have extreme nausea, which may get better over time , if you can stand it long enough. I used to eat a couple of dry crackers a few minutes before taking it. Helped a little.
You should talk with your doctor though, and let them know what you have tried, and what you are feeling. They can’t help you if they don’t know, and you shouldn’t have to suffer like that. Take care of yourself and be your own advocate! Best of luck this.

HELLO MARYLYNN: I have had major problems with vomiting, whether I take the meds before or after eating, it doesn't seem to make a difference. I guess it is just another challenge for us to deal with! My doctor suggested Biotene for the dry mouth. I hope this helps.😌

Thank you. My doctor has prescribed an additional dose of carbidopa 25mg. to be taken with my carbidopa levodopa three times a day.
