Having sinus and allergy problems and was told to take Sudafed for a decongestant because I cannot breathe at all and not sleeping because of it. I'm breathing better now, only problem is that I'm now WIDE awake and can't sleep, even though I feel exhausted. Does Sudafed do this to anyone else? I've always been sensitive to it and never take it, but right now this mama to be needs to breathe lol.
