Itchy skin could it be from alcohol?

Hello so I drink once a week mainly when I go clubbing I’m aged 26

I usually drink pints of beer, Stella or Madri and then drink double vodka lemonade and sometimes jäger bombs

I’ve noticed not all the time but sometimes around 2 days later I will get itchy skin all over my body? And it really severe itchy skin this will typically last a few days then go away

Could it just be dehydration? Or could it be alcohol?

I’m wondering if I need to stop drinking? I remember I had a liver blood test 2 months ago which come back normal
