Hi Eve. I completely understand this feeling as I have unfortunately gone through withdrawal many times. People are absolutely right - it gets worse each time, and you are more likely to get it even worse if you were to drink again now. I know the temptation is tremendous because it might temporarily alleviate the pressure/anxiety/pain, but believe me, it will only prolong the inevitable detox you need right now.
Everyone is different in how their body reacts to withdrawal. By about a week, I'm usually feeling somewhat normal and at least able to function. You will get there. Light exercise is definitely a good idea, as well as super healthy food and LOTS of hydration. I've also heard that apple cider vinegar + water can somewhat even out the alkalinity disruption caused by alcohol consumption.
Just take it easy and be kind to yourself. This happened, but it doesn't have to happen again!!
