So I Am 30 Days Alcohol Free. Was Never A

So I am 30 days alcohol free. Was never a heavy drinker but consumed alcohol maybe 2-4 drinks , 4 days a week for as long as I can remember. I’ve been having odd symptoms such as lethargy, cankersores, my skin breakouts. I’m a healthy athletic 40 yr old man- my questions is can these symptoms be my body detoxing even though I wasn’t what I thought a big drinker. Thanks in advance.
