Yep, been there done that. I got myself in a pickle once, was 111F out that day, and I didn't have enough water and had no honey in the truck. I was unloading a load of brush and ran out of water. I got so weak I could barely stand. Started eating tic-tacs that were in the truck for energy. I just knew I was going to die a stupid death. I started begging for someone to help me, and finally got one of the dump workers to do it for me for $100. While he was working at it, I quit sweating, got dry heaves, and vision was darkening. He got it done and took me to the water supply they had there for the workers. I drank a quart and filled my thermos, and was able to drive home. By the time I got home, all was well. I learned a scary lesson that day, and always have water with me and honey in the truck at all times for energy when needed.
I really hate having to learn lessons the hard way, but am so thankful I made it home alive that day!
