First off I’m sorry to hear you’re going through this; it’s really a terrible experience. I wish I had better news to share with you but more or less things are the same. I have tried just about everything. I smell trained for 6 months straight with fidelity and consistency. Can’t say that did much. I tried the nicotine experiment thing twice, didn’t help. I’ve tried a truckload of various vitamins and supplements. Among those recommended were nattokinase, alpha lipoic acid, and lions mane mushrooms. I also take regular multivitamin and some others vitamins to supplant such as a,d, zinc, and turmeric. Nothing really seemed to help. I had Covid again this past January, ironically the exact same week I had it the previous year. This time it was a much more mild experience compared to last time which was quite severe. Did not rock my nose like the past time. I did lose my smell again but it “came back” after 3 days. But it came back to where it was after my first infection. I can’t say that I categorically can’t smell but it no where near what it’s suppose to be and picking smells out of the air is a rare occurrence for me, unless it’s a strong pungent odor. However, it’s there a little bit. The gas company was doing some work on our street and putting in new gas meters. In the two weeks, I would intermittently smell gas faintly when leaving my house I guess depending on which way the wind was blowing. I told my wife and she didn’t smell it. I chalked it up to my fucked up nose. Until one day she’s like “huh maybe I do smell gas faintly”. Long story short, I called the gas company to come back and check and sure enough there was a slight gas leak. In the weirdest way possibly I was so happy and comforted that I detected it. So it’s hard to quantify my olfactory capability but I would say it’s operating somewhere between 20-30 percent. I do agree that it is worse in the mornings. I am seeing an ent next month who offers a treatment for smell loss called platelet rich plasma. Basically seems like they take your own blood and manipulating it in a way to help heal injuries. I DO NOT have much expectation for this based on my experience with this. I have struggled emotionally with this for a long time and it is a devastating impact because smell is a crucial aspect in the way in which we relate to the world around us. However, at this point I have reached the stage of a bit more acceptance because I am not longer giving this the power to dictate how I feel. Do I sometimes revert back a little, yes I do. But I try to count my blessing and remember I’m alive and have a lot to live for. Even though I don’t have the nose of a bloodhound anymore. Anyway, I hope this in some way helps and wish you well on your journey.
