I m experiencing very regular lightheadness. Dizzy. Like I m going to faint but I don t. Generally I m really fit and active but my body feels heavy lately and my muscles tight. I keep getting pains in my right hip thigh and knee ( I rub on magnesium and this seems to help). I feel I m urinating quite a lot, maybe twice an hour, but I do try to drink a lot of water. I m also experiencing pains similar to period pains but there not during my cycle. Been quite a heavy drinker for many years but upon feeling this way I have given up and not had a drink for 2 months. This seems to have made the lightheadness more frequent. Also feeling regular fatigue when I m normally full of energy. Craving more sugar foods when I generally eat a very very healthy diet with a super low salt and sugar intake. I m a smoker aged 40.
