Yes vitamin D! I feel so much better taking the supplements, I was shocked my levels were so low last fall, I should get an rx for really strong strength but I have just been taking double the over the counter ones.
Hang in there Moosey, you can do this, look how much you've already made it through!
Hope son is ok, didn't you guys do one of these sleep studies recently? I can't remember the results of last one or if u posted it. Hoping it goes well
