Hello @pickleballbob and welcome to Mayo Clinic Connect. Because of what you shared about periodic episodes after two years, I thought this discussion on covid crash may be really helpful, so you will notice I have moved your post into this discussion. Members such as @rinadbq @aae @welchllb and @sonyamagee1964 have all shared about experiences with these episodes/crashes so I hope you can find some ideas around what you are going through.

Does there seem to be any pattern just prior to or at the onset of an episode in terms of symptoms and/or environment that could be a trigger?
