I attended in February and found the information to be useful. The format of the classes were atrocious as you attended a class for close to four straight hours on two successive days. Although I was able to pay attention during the first two hours of each class, I lost focus afterwards, During the last hour of each class, I felt that their words were washing over me like the water from a shower. The words, like the water, did not penetrate below the skin. After each class, I was unable to function for the rest of the day. After the second class, I had to stay in bed for two subsequent days. If they had sent the information to me and allowed me to process it at my own pace, I would have been able to process the information better and retained it longer. I really like Mayo Clinic in general, but I feel that they need to redesign these classes and ask for the input of people who suffer from Long Covid to design it better.
