A member asked:

Hydroxyzine and benadryl (diphenhydramine) both give me similar horrible side effects, but doxylamine does not, is there a reason for this?

Both Hydroxyzine and Benadryl (diphenhydramine) are highly sedating for people, while doxylamine has less sedating effect. The newer antihistamines have very low or no sedating effects.
