I always clean my teeth 2-3 times a day, i eat reguar small meals and drink lots of water, recently the same time as my PMS started, my period DUE and my IBS worsened my breath has continually got worse! Its so embarrasing, if i dont have a drink within as little as 10minutes i have a horrible taste and my breath isnt nice, it can be as much as 10mins after doing my teeth, i try to hide it but nothing covers it!!
