When my husband was in treatment, we were told again and again to get ahead of the nausea — which really meant taking the nausea medication before one got nauseous. Once the vomiting starts, it gets rather difficult to bring it under control. It is not a sign of weakness to need to take the anti-emetics, it is just a way of helping the patient get through the treatment. If your husband has a feeding tube, make sure you give him water with every feeding. It’s important to do that so he doesn’t get dehydrated.
