it's not at all unusual to have all manner of odd physical symptoms and issues for the first year of sobriety. Shakiness, moodiness, depression, anxiety, strange sweatiness, sexual issues, emotional issues, weakness, boredom, loneliness, anger, frustration, grief, fear, weight gain, weight loss, panic attacks, blissfulness, extra energy, not enough energy.....
you name it - it can happen during sobriety's transformation from addiction to living life.
as has been mentioned - if you have physical concerns; speak with a doctor. If you experience emotional or psychological concerns; get yourself a qualified therapist.
Keep at it, keep supporting your sobriety and you'll be free!
