It was so bad that when I would go on vacation or eat too much, I would pay for it. For the first 2 days of a vacation, I always felt miserable. My stomach hurt, I would be hungry but not want to eat for fear of feeling even more horrible. I felt sick and bloated and who wants to vacation like that??
