Cisplatin redefined the word nausea for 9 days each dose. It doesn't cause hair loss. It can and did cause severe tinnitus, which stopped me getting the 3rd dose. Others around me had similar experiences with nausea, some worse than others. I think it depends on how well you react to the anti-nausea drugs as to how bad it gets. Cisplatin can cause permanent hearing loss too. I have no experience with Erbitux, it wasn't offered as an option for me.
