@hopeful33250 Hello. My husband did not start using Vyalev. He is currently using an Inbrija Inhaler to help with 'off' periods. To date, he has not seen any significant improvements. His stomach issues; however, he is addressing the old fashioned way. . . . he makes sure he moves every hour - whether walking upstairs and back or walking around the house (this keeps the stomach mobile and awake), he eats two or three animal crackers or graham crackers every hour (this also keeps the stomach awake), he drinks a cup of warm chamomile tea 15 minutes before each Carbidopa/Levodopa dose (this actually helps open the flap at the bottom of the stomach leading into the intestines) and he only eats protein for his evening meal. All of these things help the stomach absorb and push the Carbadopa/Levodopa through the stomach and into the intestine. He likes bread and carbohydrates so he has lots of pasta, bread, bananas and plant based milks and products (cream cheese, etc.). It's boring - but we find hope and joy in having diminished nausea. Initially, he lost 30 pounds due to nausea. He has gained a little weight back. :). Hope you feel better.
