My eyes have been crazy itchy lately, not sure what's going on but my regular eye drops don't help. Benadryl however does, the problem is I take it and in about 15 minutes start feeling better, then about 20-30 minutes after that I start wondering why I'm so sleepy. Then I'm pretty much done for at least a few hours.

Right now I'm on minute 20…

@paul if you are looking for something in the same class as Benadryl, try generic chlorpheniramine. I get mine at CVS. Although, I’d try Allegra first. I also second the Ocusoft recommendation from @stevenortiz.
