Idk if im getting sick but recently ive been serious about getting sober, have 9 days
Could it be withdraw ?
Ive been having a stiff neck headache but also noticed racing heart rate , cant sleep, anxiety , involuntary small jerks or noticeable trembles in my leg like im nervous.

maybe months I don't know your situation.but it takes time for the body to recover usually mentally it could take up to two yrs.but it will definitely come back health and mentally.hang in there brother .
