I stay dehydrated. lol. I was MUCH worse before I really started researching vaping + dehydration.
When I 1st started vaping I was a 2 soda a day guy. As in, thats ALL I drank. 2 sodas at the most.
I could go months without a single sip of regular water. I drank Soda, and rarely, some juice/beer/liquor/coffee.
But yeah, you really feel drained and sick if you vape all day and only drink 2 sodas, 1 right before bed....
So, I started hydrating. Unfortunately, hydrating isn't the great cure-all for all your problems.
In fact, since I began drinking 4-5 glasses of water a day, I don't feel GREAT or fantastic... I just DON'T feel sick. lol.
