Hi kkw
Welcome to SR
That all sounds pretty common kinda stuff to me...I always advise people to see a Dr if they're concerned at all about how they feel though, or if they've drunk for a long time. Detox can be tricky for some of us.
I know a lot of people seem to use Benadryl but it's actually an anti allergy medication, not a sleeping aid - I'd ask your doctor for advice if you're having trouble sleeping.
The fact is - this is very early in your sobriety - the first couple of days are always rough...but they do get better.
You'll find a lot of support here - you're not alone
