Viberzi has really been wonderful the last few months. Changed my urge to run to the bathroom several times a day! Recently I have been experiencing dizziness and light headed feelings. I was on vacation and became extremely dizzy (1st time) and thought it might be due to sun burn and dehydration. I went to the ER and had some blood work done and they gave me fluids. I did the ER because I knew they would get results fast and I was on vacation. With that said, they said my labs pointed to dehydration. I am home now, hydrating, and paddle boarding again and tonight I felt a bit light headed again. Been getting little lightheaded feeling every so often. Is this common with Viberzi? Do I need to double my fluid intake now? I love the pill but I can't function if my head isn't right. Thanks to any and all who answer this.
