I am 33 weeks, I am having the hardest time trying to fall asleep at night. As soon as I lay down I feel a tightness in my throat and chest and when I am about to doze off I suddenly wake up with a gasp or snore. I have tried all positions, propped up with pillows, on my side etc. I am starting to feel really exhausted as I don't manage more than 5 hours per night often interrupted by trips to toilet, baby kicking etc. does anyone else experience this, and is there anything I can do or do I just have to endure it for anothe 7 weeks? This is my second pregnancy, it was never so bad with the first. Thanks
