Those things can really mess ya up! The man gets allergies like crazy. He takes something and gets super groggy and out of it. I'm pretty happy that I don't have any allergies!It doesn't take much! I took 1 Ed a hist. That's it! And then just the affect that allergies have on my brain bc my sinuses get all stopped up and my heads all full so I'm just confused as crap over here. I do feel some relief from the meds though! Thank the Lord. This time of year is hell for me!
