FYI.. Taking bendryll can cause problems when you try to stop taking it. It is not as bad as zyrtec but there is case study that both of these drugs can have a "withdraw" effect when you stop taking them.

I took both of these drugs for years, especially zyrtec and I was in the percent of people that had serious withdraw effects. Rash and extreme itching, which made me think I needed to keep taking the drugs, was actually caused from it.

I am taking 5,000 iu of vit D now but I have never been tested. I hope it is safe but without testing i dunno, but I really believe I need it.
