I really struggled with my breathing with material masks, but have found the disposable surgical masks ok. Bearable enough to have started driving home with it on! I’d rather wear reusable ones, but needs must. Wearing masks with glasses is difficult particularly in colder weather, but found shaping the metal bit further down my nose helps with avoiding misting up. Even better would be a longer nose! Not something I had wished for before! I will continue wearing masks when I need to. I believe it does give you some protection, but no one has ever said it would protect you completely. Or vaccines. This virus is doing what viruses do, mutating. We will continue to need boosters in years to come, just as we do with the flu. Hopefully only once a year, with a better understanding of how this virus works.
I keep my masks in a regularly washed bag in my handbag.
