Hi, Mariam, Here's a "some do-some don't" athought. John's Doc told him to always have a gauze drain pad between his skin and the peg button and change it frequently to protect his skin. [I have read that some folks here did not use the gauze. [it is a little square with a slit running toward the middle] Altho we all know it is natural to "stew over things", hopefuly you will express your worries and concerns here so that we may be able to head some of them off before you lose too much sleep or wrestle with those bad dreams. You, as the caregiver, will need to rest when you can. Amy in the Ozarks
