This past summer, i dehydrated and fainted. I also had a ton of bruising going on although i heard that garlic might have been the cause of that. Now, i am exhausted so far i have taken naps for up to three hrs a day plus a full nights sleep and have a nauseous feeling right before or after i take a nap. what is going on? should i see a doctor? is it my sugar levels going out of wac?
