Welcome lillith - it's so good to meet you.
Yes, it is normal. I was achy, disoriented, sensitive, emotional - for the first couple months. I drank for 30 yrs. though - so hopefully you'll feel better sooner than I did. I had to learn to live in a whole new way, without numbing myself. Facing the world clear headed takes some getting used to. Be proud of yourself for seeing what needs to be done at such a young age. To go back and be 24, and not drink - my entire life would've turned out so differently.
