Hello, is it okay to switch randomly to Linzess on certain days when on a Amitiza cycle? I have stock of Linzess that no longer works, so I was prescribed Amitiza. (It does work sometimes). On days that I feel Linzess will work, and I am overhydrated and won't be in any hurry next morning, could I skip Amitiza for that day and used Linzess?
