Had my second vaccine a few days ago and felt miserable for several days from a dehydration headache that stuck around. I was eventually able to sleep it off, but want some better strategies for the next time that happens. What are your tried and true ways of rehydrating (relatively) quickly?
Would love to hear any advice you have, the more specific the better. (What you drink, amount you drink, when/intervals at which you drink, what do you eat with it, etc...)
If I understand correctly it's possible to over-hydrate and not absorb what you drink. I wonder if I was doing that and if I made my headache last longer. Are there ways you can tell if you are hydrating adequately or too much?
