Welome to the group. I also have ET. Have had high platelets for over a year but was just diagnosed this past August. I am on low dose aspirin and 500 mg of Hydrea on MWF. I was very tired at first getting use to the meds. Doing ok now. Have a tired day once in a while but thankful for every good day. I go this coming Thursday for another blood draw and see where I am now. Praying the best for you!!!
