den eke power eka naa. 10mg walata wediyen nedda?
machan
cetrizine bonna epa
eka awilla
histamine antogonist or antihistamine drug ekak
dont take it when u wanna go sleep
cetrizine or that matter for any antihistamines are used to treat allergies
from hayfever to acute rhinitis
go see a doctor
if u were to keep taking it, like u said u'll get a resistant plus create a psychological dependance as well
not to mention the damage to ur kidneys
cetrizine barely passes ur blood brain barrier
it stays in ur blood most of the time causing any sedative effect wat so ever, but mostly being excreted by ur kidneys, u have created a dependency that's why it doesnt make u sleepy at all.
worst case scenario, in sometime
u'll be popping cetrzines like candy to help u sleep
my advice
go see a
Physician
Neurologist
or
Psychiatrist
