I don't have an answer to your question, but I do know where you are coming from. I had my nose broken as a teenager, and spent many years with a horrible sense of smell afterward. I hardly ever wore any fragrance in that time, because there wasn't much use. I couldn't appreciate it anyway.
Within the past year I began to notice my sense of smell returning. I can't explain it, but I"m thankful. Since then I've gotten drawn into this hobby of fragrances, and I'm loving the journey.
I wish you luck.
