I too have had the same experience and I have NEVER had bad breath in my life. I will be seeing my GP tonight and intend to raise this matter with him.
I've noticed a lot of people have said that they get bad breath on it,i too am very concious of it,i don't know if my breath actually smells bad but u can kinda taste it,anyway for the weight results im getting im putting it down to a minor let down,in three months il b thinner and the bad breath will go once i stop taking the tablets so its all good
