WTF Happened?

Something went wrong last night, and I'm not sure what.

I ate my taco salad about 12:30.  Everything was fine.  I ate my burger and dog at about 6:30, then followed it up with a cup of coffee at the bowling alley around 7.

About 7:30 I got dizzy as all hell.  I almost fell down.  It felt JUST like a sugar spike.  I fixed my own coffee, so I KNOW it was splenda and creamer.  I was using a generic powdered creamer, without nutritional info.  I'm not sure if there was something in my burger/dog that added sugar or if there was something in the creamer, but I was definitely having a sugar issue.  Some friends sat with me, got me water, and it passed in about a half hour.

Scared the crap out of me tho.  I have no idea what triggered it.

This morning, I woke up exhausted and sick.  I SHOULD have had plenty of sleep, but my body didn't seem to know it.  I'm suspicious that it was the aftermath of a sugar crash (which will generally happen after a spike).   I was so tired I was crying while trying to get dressed, and felt like I was barely restraining a temper tantrum.  Then the dry heaves started every time I tried to move.  Mind you, I went to bed just a few minutes later than normal, and didn't have trouble sleeping.

I ended up calling in to work and going back to sleep around 5:30 (I get up around 4:45).  I slept til 10:30. I still don't feel quit rested, but the tantrum is gone.

...Wish I knew what caused it.  This scares me.

Addendum: the burger & hot dog seem fine.  Then I found this page. It shows that SOME powdered creamers can have up to 8g carbs.  I used two packages for my size cup and DOWNED it. So I potentially threw 16grams of carbs into my system, in liquid, easy-to-digest format in the course of under 30min.  I BROKE me!!! Note to self: Use my OWN coffee creamer when in doubt.  Mine only has 2carbs/packet.
