Be prepared for it to be gone a long time. It took me 4 months to get my smell back- and I warn you that some stuff won’t smell the same once it comes back. For example, the smell of mint in my garden came across as a mix between gasoline and rotting flesh. That took a lot longer to get over but it does get better. For what it’s worth, the afternoon of the day I went swimming in a local mineral spring known for therapeutic qualities, my smell sense came back. Got any mineral springs nearby?
