I am wondering if there is maybe one person within this research group who has had some success with the nicotine supplements for Long Covid - massive dizziness!!! . It will be three years next month in April when I was clobbered with my second Moderna vaccine and I have been a cripple for all practical purposes since then. Walking with a cane and still swaying and staggering like a drunken sailor. Have taken 4 Covid tests over the years, all negative, but the vax did me in. Have of course lots of other symptoms but the never-ending dizziness is hard to handle, especially after such a long time .... ;-( thank you kindly
