I am 77 years old and have been weak and sick to stomach for 6 days,,2 days with dirreaha ..the rest of time just no energy....can be on my feet for 5-10 minutes at most, then I have to lay down...Blood pressure was 172/103 on Monday and normal rest of week...Trying to eat however no desire for food...Took a water pill first 3 days I was sick,, thought that might make me feel bad but stopped taking two days ago...lost 8 lbs in 5 days..I think that was water.....sorry, had for me to concentrate...
