Trev, I too had concurrent chemo and RT with 4 rounds of cisplatin, once a week. The injection itself was not a big deal and I could still drive back home after treatment but about two days later, nausea appeared and I couldn't stand the cooking smell in the kitchen. Make sure your doctor gave you the anti-nausea drug to take before meals, or else you won't be able to eat. I remember throwing up three times during treatment. Other than that, you will feel physically and mentally weak. Watch out for depression. No loss of hair in my case. Advice in above posts is worthy of noting and I hope that you can overcome all the discomfort very soon.
