I know it gags you and makes you feel sick even if you don't. I had similar problems but nothing helped and be careful about what you take because some things can cause unpleasant side effects for the baby. I would gargle water that had a tablespoon of apple cider vinegar in it and it helped a little. Avoid fruit juices like orange juice and milk also, that reduces the amount of phlegm you'll produce.
