I've been suffering from a sinus infection and terrible allergies for a week now. I can only take Benadryl at night because it'll knock me on my ass if I take it during the day. Claritin doesn't seem to be helping so my dr prescribed me Sudafed. I'm really nervous to take it...Especially because you have to sign your life away when picking it up at the pharmacy. Has anyone taken Sudafed for bad congestion during pregnancy?
