Thanks both,I have been on lanzoprazole way before surgery as I have allways had problems with acid,as I am 3 weeks post op and have only just started on mashed food I am wondering if it's to do with the change from liquid to mashed food,I have been very careful what food I have been introducing also so possibly going to make docs appt this week as I also have had practically continuous nausea since the op as well,thought I would get them both checked
