Symptoms and stress

Florida was great! Great time with great friends and family. Americans are wonderful. That greeting of Have a nice day together with a look in the eye and a lovely smile sets you up for the day!. Used a scooter to get round and glad I did as 5 min walk in the sun and I was knackered. Never h.eld anyone up ! Great. My afternoon tiredness is coming terrible especially at work! . I tend to go for a walk somewhere so no body sees me dropping off, ! Any tips?
