Zyrtec and mood swings

I was taking Zyrtec every day for the last 3-4 weeks. It is the best OTC medication for my mild, but annoying allergies. I stopped taking it yesterday for the first time and had the worst migraine with nausea and vomiting that I've ever experienced in my life. I didn't take it again today. I'm feeling a migraine coming on, and would rather take the Zytec than go through that experience again.

I love the fact that Zyrtec works wonders for my allergies, but not how it makes me feel. It effects everyone differently that is for sure.
I have been severe with my mood swings and soooooo tired even if I have taken it at night. I can't recall any weight gain over the past year because I have been on a diet. I have had the heart flutters, nausea and dizziness. The worst I can say though is the aggressive behavior, very easy to snap and crazy thoughts. This is not good when you are a stay at home mom with a 3 year old and 1 year old. I have recently taken myself off of it and feel happier and so do my kids. If you or someone you know has to take it please take notice if any of these side effect occur and switch meds. It affects not only you, but the ones you love around you.
I would rather sneeze.
As for withdrawals; I get severe headaches, sleeplessness, and itchy.

I think the hardest part - for me - was even to concieve the idea that Zyrtec has all of these side effects.

I've been taking Zyrtec on a daily basis for about 90- 110 days a year due to really bad allergies. We live in the NY area which produce alergans most of the year.

After trying almost every antihistamine, Zyrtec seemed at the time as the best drug since it handled the allergy while eliminating the drowsiness almost completely for me. Being happy that I was able to maintain normal life during allergy periods was almost a new concept for me and I was really grateful for finding this drug.

Unfortunately, being almost blinded by the allergy-fighting success, I neglected the attention to the side effects. I guess I'm falling into the unlucky 2%. I had almost every side effect: Irritation, mood swings, gaining weight, dry mouth - just name it.

Recently, my wife did some research because we got to the point where I would fight with her over anything. I can testify that my tolerance level hit the ground. Anyway, she got my attention for her research results which turned a red flag for me. In addition, this year my body seemed to not respond anymore to the drug and doing my own little research revealed that it is very likely that you need to rotate different drugs every few months.

So I decided to get off Zyrtec and switched to Benadryl Allergy which I take every 4-6 hours. Yes, it does make me drowsy for about 15-20 minutes but it works. What's more interesting is, I've been about 10 days off Zyrtec and I am shocked to realize that I'm slowly getting rid of all the side effects associated with Zyrtec.

That being said, I would like to emphasize that this was my own individual experience and it may not be the same for someone else. But it is pretty disappointing for me that i cannot use this drug anymore on a regular basis.

Is any one having menstrual problems? I have had a lot of cramping and little to no flow-which is unusual for me-I feel like I am constantly PMS-ing
and I want to eat all the time! The allergy problem is gone but my ovaries
are killing me and Im gaining weight!
