<human>: Can you give me a shortened version of the text?

Did my first half-marathon on Sunday - I was underprepared and the day was a lot hotter than I expected.  I also didn't bring water (NEVER AGAIN) and got pretty dehydrated.  The last three miles were brutal - I needed water worse than anything I've ever needed in my entire life, there was no shade, it was much hotter than I expected, and there was no water available.

I know I suffered heat exhaustion and toed the line with heat stroke - I had goose bumps all over, wasn't able to sweat anymore, and when I did cross the finish line I was really confused - I couldn't seem to find the water station despite people pointing at it.  It just seemed too confusing to process.

Before anyone says anything:  I LEARNED MY LESSON.  I WILL NEVER, EVER, EVER ATTEMPT ANY RUN AGAIN WITHOUT MY OWN WATER. EVER.

That said - it's been two days and I am still struggling with exhaustion and occasional dizziness.  Got any suggestions?  I'd go to the doctors but whenever it gets bad I head to the store, buy a gatorade, and then feel better, so I think it's just electrolyte imbalance (or something?)

Still...I'm tired of Gatorade, and  I don't know if this is normal or not.    I ha I'm a pretty new runner - never attempted anything like a half before, not really training with anyone knowledgeable.
<bot>: Ran 1st half marathon on Sunday, suffered heat exhaustion, electrolytes possibly still messed up.  Suggestions for recovery?
