Anyone else had problems keeping medication down?

Hi, I've recently been diagnosed with gastro-oesophageal junction cancer. I'm waiting for some final staging results and confirmation of when my treatment plan will start.  But, I'm really struggling with taking my normal medications (I'm type II diabetic on insulin and take meds for another chronic condition).  The continual acid reflux/bile secretions my cancer is causing makes keeping my medication down  really hard.  Has anyone else experienced this and found something that helps?
