Hi there, First of all, let me congratulate you on your sobriety. Staying sober for that long is quite an accomplishment, and you should be very proud of yourself. I m so happy for you. Low energy and fatigue could be due to a number of things, but the most common cause is poor diet and poor sleep hygiene. I d first recommend eating a diet high in fruits and vegetables, and try to avoid processed foods and high amounts of sodium. Second of all, I d recommend you get 8 hours of sleep at a regular time every night. Try to avoid napping during the day. The third thing I would recommend is a regular exercise program - at least 5 days a week. I d make these 3 lifestyle modifications and see if your energy level improves after about a month. If you still fatigue, I d have your doctor check your thyroid levels, as low thyroid levels can often lead to the symptoms you are having. I hope I have answered your question. Feel free to contact me if you have any further questions.
