I thought the Glucose Drink tastes nice
Or at least, not that bad. It wasn't as bad as I remembered with my first pregnancy.
Later I realized I had taken a zinc lozenge to fight a cold and my taste buds were suppressed and whack. So if you want to try and diminish the nasty taste of the glucose drink, have a zinc lozenge in the morning. You won't be able to taste anything properly so it will go down easy.
