I am sorry to hear your news. Navelbine might be one of the best types of chemo to tolerate. You can probably get a list of possible side effects from your doctor or 
www.navelbine.com might work. Most drug companies have a website for each major drug they produce. 
I took Navelbine in the past. It did not cause hair loss. I did get pretty tired for a day or so afterwards. My blood counts went down slightly, but never down to dangerously low levels. I took supplements for that. Whatever you decide to do please do it soon to prevent more mets. Some of us take Milk Thistle and drink beet juice for the liver. I started taking Milk Thistle when I was first diagnosed 10 years ago and never had a liver met. I still take Milk Thistle every day. I eat beets or drink beet juice occassionally. I just had an ultra sound of my abdomen. My liver is perfect. 
Good luck. Take care.
