Have everything on hand just in case. You may breeze through and need nothing but best to be prepared. Make sure you have phone number of the hospital Oncology dept. Have medication for heartburn, headaches, nausea, constipation, diarrhea, vertigo. I took anti histamine tablets prior to chemo but the nurses offered me those. You will be able to cope with it all if you are prepared. The heartburn caught me most by surprise but this is not overly common. Be prepared for taste changes and keep your water intake up, even if you have to mix it with other flavours. Many people find sparkling water more manageable. Sounds scary but is actually more annoying/frustrating.
