Mast cell stabilizer symptoms and conditions

I just found out about the hives issue when going off Zyrtec. The incredibly annoying thing about this is that the reason I went on the Zyrtec is because of hives so now that I'm trying to see if my hives are gone by going off the drug I can't tell because that's the withdrawal symptom! I used to have to take up to TWO pills a day to deal with my hives and now I can go about three days since I started using traditional Chinese herbs (through a practitioner) to work on my hive issues. Part of me thinks that the herbs are working but it's impossible to know because of the withdrawal issues. I would not have taken this drug for hives if I had known that was what would keep me from being able to stop taking it. I'm really aggravated!
