Feeling sick after too many carbs?

walkingmommy2014

I have been doing a moderate protein/high fat version of low carbing and have been getting really great results. Long story short, it has been quite some time since I have eaten more than 40ish carbs in one day. My family and I were having a particularly hectic day of errands and I just did not have it in me to wait so late in the day to eat lunch, so we opted for fast food. I had a burger and fries. At first I was fine, but after a few hours, I felt very sick. I puked twice and my husband commented that it really smelled especially bad. I also felt extremely tired with intestinal cramping. Has anyone else had a bad reaction after eating something "bad" after a long period of low carbing?
