Just keep drinking your 4 litres of water, get yourself some listerine strips and some Dentyl (Listernie itself has alcohol in it), and just remember WHY you are doing this diet. Its a short term problem. I had to deal with a lot of clients whilst I was SSing and I actually apologised to them if my breath was pongy, telling them what I was doing and why my breath might be pongy. Not a single one minded and all were very impressed at the weight loss. PEOPLE DO UNDERSTAND!!!!
