Hello! The other day I posted about what cold medicine if any was safe during the first trimester. I only received a few responses about tylenol, cough drops, and certain robotussin being safe. What about alka-seltzer and emercen-c? My husband and I had the same symptoms and both went to sleep at 9 p.m. last night, only he took alka-seltzer and I took tylenol and he is a new man today and I am still struggling to get through the day.
