Allergic Urticaria
"I had chronic ideopathic urticaria for a 6 months before I found anything that remotely helped. Once I got on a cycle of of 40 mg hydroxyzine before bed and 150 mg ranitidine +5 mg of levocetirizine in the mornings I started to have noticeable improvement. After another 4 months my hives were completely gone. 

Of the three medicines, the hydroxyzine by far provided the biggest impact. This medicine stopped hives from forming during sleep and the anti-anxiety component definitely helped sooth my mood and get me to sleep more quickly.

I will say that this medicine gives you some really wacky and vivid dreams. It also makes you feel very groggy after taking it, lasting well into the next morning. Those symptoms are worth it though."
