Mornings are absolutely dreadful. I have OI and getting out of bed is a challenge that I have so far managed to do for most of the 24 years I have had this disease. I am thinking it is mostly due to overnight dehydration, so try to ensure I drink some fluids before bed, but still I wake up with a headache, coat hanger pain, palpitations, sweating, breathlessness, and sometimes dizziness, and my pulse pressure is very low, as is my morning blood pressure, though lying is a lot better than standing. I have also noticed my urine is very concentrated first thing as well - anyone have all this and any ideas how to improve matters? I did try raising the head of the bed but that didn't help much.
