The horrid taste & bad breath does get better. I had that too. My breath was worse than the dog's & that's saying something! Brush your teeth & tongue frequently. Also, my LLC recommends RetarDex mouthwash & breath spray. They helped me loads.
It gets better to the extent that you completely forget about it! I think the bad taste had gone by week 4 and I asked a few people and no one noticed the breath after the first month.
