allergies
"My allergies are the worst in the morning and this medication directs it be taken at night.  I've tried that several times and it is no help whatsoever.  Just before writing this I had to take Benedryl even though I took this medication last night.  Very disappointed in this product!  The couple of times my allergies kicked up at night and I took it this product did not help at all.

That said everyone is different and I guess if you want to try it and see if it works for you go ahead.  But if your allergies are bad in the morning it will not help at all."
