My reason for asking this is, I've been taking medicine for my allergies for the past couple of months, and I haven't had a lucid dream or anything close to one.

Also, my dream recall's gone to shit, and I wake up completely disoriented sometimes, not even knowing what the numbers on my clock mean. I take it before I go to bed, so that might be the cause of the problem.

I take:
-Singulair
-CVS Brand Antihistamine
-Vitamins

I'm mainly concerned about the CVS medicine, but the Singulair could be doing something as well.
