Tiggy you poor thing, I was thinking Brauers too. you can give four doses in 2 hours so prob best to give around 5.30, 6, 6.30 and 7pm. I do find it good. Worth a try I suppose.
I honestly and truly think you are a most amazing mother and person in general. I absolutely admire you. I lose it when coco wakes at night so I can only imagine how your sleep deprivation must be. I think the sleep aponea sounds like it could be linked, and I just hope you can get into the hospital asap.
thinking of you and here for you to vent to. Sorry Im not much more use than that. xoxoxo
