Of late, feeling foggy, tired and lethargic. Especially in the morning. Takes a while to really get to an optimum energy level in the morning. Was diagnosed with ear imbalance a few years ago but there is no dizziness I feel, just foggy. Follow healthy eating habits with some exercise 2-3 per week. Used to take multivitamins and vit. D supplement which I stopped in the summer. Live in Canada so not sure if the weather has a part to play. Appreciate your guidance. Plse write to YYYY@YYYY
