Shaky and faint after alcohol

hello, for context I’m a 25 year old female. I eat healthy, go to the gym and play sports. I don’t drink alcohol that often (maybe once a month/every 6 weeks) but the last few times ive drank alcohol I’ve started getting very weird symptoms the day after.

the first one was when I was on a girls trip and we had been drinking for a few days on and off. On around the 3rd/4th day we decided to go for brunch. I had actually woke up fine and I was happy I had no hangover. We ate brunch and then suddenly when i was walking in the street I started feeling very unwell, weak and shaky. I had to lie down on the street, my body was shaking and I was so scared I was going to pass out. This lasted around 40 minutes until I eventually got sick and started feeling better. I’ve been drinking for 7/8 years and nothing like this had happened before.

it also happened to a lesser extent 2 weeks ago after a wedding. The next day, I had just started eating my lunch and started feeling faint and shaky again. It wasn’t as bad this time but it still lasted quite a while.

on Sunday I had 4/5 drinks and It still happened me to a lesser extent the next day.

Basically I’m just wondering if this has happened to anyone else and if so did you go to the doctor? I’m booked in for a blood test next week as I’m worried I may be deficient in something as my energy levels have been low since Sunday too.
