Hi. I experience excessive sweating when I am busy or have exercised after which I am left drained. Generally I do things slower than before because I tire easily. Sometimes I wake up in the early morning hours feeling very cold and shivering and no matter how much I cover myself I don't become warmer. I use a hairdryer and warm under the blankets several times. Eventually, I fall asleep again but when I wake up I am extremely warm. When I uncover myself I become cooler. My heart also beats very fast. About 2 months ago I took 2 med-lemons 6 hours apart and read later that u have 2 take 1 in the morning and 1 at night. The water poured out of me and I was drenched. I have been experiencing this ever since. Could the Med-lemons have affected my nervous system or could something else be wrong with me. Please help what can I do?
