Does hydroxyzine cause you side effects? When I took it before bed when I did sleep I got nightmares and found I couldn't be productive until the afternoon. I started taking half a dose, to turn me less into a zombie. Still the itching was always present; worse at night with our elevated histamines. In truth I think the only thing that would knock me out enough to not be kept awake from itching was a sludge hammer, once again we're talking negative side effects.
You may not be able to force yourself to drink fresh or fresh frozen cilantro, yet from my experience the capsules success rate is extremely low.
