HIVES After Drinking Baking Soda Water!!!

Okay, so I posted yesterday that my hives get worse at night and someone said that it was because my body was more acidic at night and to drink baking soda water. I woke up worse this morning than I have been the entire time. Now, I may have overdone it on the baking soda water so maybe that is it. I also have been suspecting that my hives are a result of a yeast overgrowth and right after drinking the baking soda water last night, I read the yeast thrive in akaline environments! Is this true? Please help me!
