Mike!  Definitely!  I was so sleep deprived yet I didn't want to go bed or have a nap no matter how exhausted I was.  It's an awful feeling really to be afraid to let your body rest and get the sleep it needs.

Batch, Yes I've been taking the 50,000 loading dose of D3 as you recommended.  I will stay on it for 12 days.

Another CH last night which started at 2:10, started the oxygen by 2:11 and by 2:15 it was gone!  Went back to bed after 15 minutes on the oxygen and slept soundly till 7! 

Carol,

Have you given the Benadryl (Diphenhydramine HCL) a try?  The pollen count is fearsome these days making an allergic reaction the real problem.  An allergic reaction triggers a flood of histamines.  When that happens, none of the CH preventatives will be effective...

Diphenhydramine is a first-generation antihistamine that passes through the blood brain barrier to block H1 histamine receptors on neurons throughout the brain and in particular, the hypothalamus and trigeminal ganglia.  Once blocked, vitamin D3 has a much better opportunity to prevent CH.

I've been using Children's Allergy Medicne, Liquid Benadryl (Diphenhydramine HCL).  12.5 mg (5 mL in the measuring cap) in the morning and another 12.5 mg in the evening prior to bed.  It works like a charm.  It also enables me to take lower the dose of vitamin D3.  I'm back down to 10,000 IU/day vitamin D3 and the Big Leaf Maple pollen is blowing around like a yellow dust storm.

Do try to see your PCP or neurologist for the lab test of your serum 25(OH)D.  Knowing your present vitamin D3 status with this lab test is important.

Take care and please keep us posted.

V/R, Batch
