Alcohol advice

The last 4 years my go to drink has been cider, I’m not really a fan of anything else. The last 4 years I have been perfectly fine just drinking that apart from the odd hangover.

Then in November this year I went to a party had a few ciders and about 3 hours later came down with the shakes and feeling like I needed to vomit badly, I put this down to having to much and not eating enough/drinking water.

BUT

This month again I had a party but this time literally on drank half a can that was it, and this time I ate a lot and drank a lot of water. But again 3 hours later I get the shakes and the feeling I need to vomit badly.

Anyone had this happen to them? Not sure if it’s worth a trip to the doctors because this to happen suddenly worries me
