I have a very bad gag reflex when entering public toilets, especially if someone is just leaving, unsure of what I will smell or find, and lately have vomited a couple of times, it s getting worse, I have always been a bit like this, since the children were born, wondering how I could cope with changing nappies, but it turned out that was totally different, loved them and no problem, but now it s interfering with my life, eg travelling etc.
