I have a bad taste in my mouth too, I think its just hormones ur body does crazy things
Maybe you just need to drink more water? you may be dehydrated.
i would say dehydrated or could have sugar issues.
Thanks guys been to my GP and she has changed my iron pills and told me i need to eat little and often to keep my levels up. She is keeping a close eye on me because the taste caused severe sickness so am now also on anti-sickness tablets.
good luck hope it gets better.
