Possibly. Some people recover their taste overtime from chemo and this has not been the case for me. I cannot eat any type of meats as it is like I am eating a ball of greasy fat. Every once in a while not so much the first day before it turns to a fatty taste. Eating veggies, fruits, lentils mostly. Cold frozen yogurt, ice pops, ice cream taste good.
Never thought about spearmint flavors other than I bought a non-compliant cheap bottle of a flavor called Snowball by Coil Vapes along with a few others. @NolaMel may be able to speak to this being out of Nola. This is described as a creamy spearmint ice cream stuffed sno-ball with double condensed milk. How long I will be able to taste it, time will tell.
Have you tried Peppermint or Honey Lemon Cough Drop? I make a version of HIC's Heart of Andes with some changes that is my ADV. I would be happy to send you some to try. I personally don't care for Spearmint. I have been thinking of making up my version of Heart of Andes with Holy Vanilla to try. That just came to me recently so I know I need to try it now. I also have an Icy Lime Slushy you might be able to enjoy.
