In the first day or two, I had a headache and generally felt unwell. By Wednesday the chronic exhaustion had settled and each afternoon I crash to bed and sleep for approximately 3 hours. I have nausea and just feel terrible. lethargic and depressed. I am double jabbed, I am also in my early 50s, when did the lethargy lift?? I am self employed and have to cancel all my work this week. I am starting to get worried as the lethargy is so horrible. No appetite and nausea off and on. When does it reduce? When do you start feeling better. Its been a week (although it feels much longer)...
