It is the little things that make life more bearable. The "little bit of sinus pain" turned into more than enough to stop me from sleeping or coping well today at all. Pharmacists all tell me that I can't take anti-histamines whilst pregnant, but various people have told me otherwise. So I called Mothersafe and got a completely lovely woman who said they get regular calls about it, and recommended three options that have all been shown to be safe by all normal standards. One of the three I had at home, and am now feeling much better.
A fantastic service manned by fantastic people in my experience.
