You’re not alone! I have had cisplatin and I also had a side effect of taste change. It peaked about 3 months after treatment, then started getting better. It took about 6 months or so to finally settle down. I also have peripheral neuropathy as well from treatment in my feet. The neuropathy has continued- I am at 11 months past treatment, so now I am trying Neurotin to help slow or stop progression. So far the Neurontin is helping, it’s only been a few days but I’ve noticed a positive difference. Super low dose just to start.
