can needles cure you? acupuncture?

in taiwan i did acupuncture treatment and took herbal medicine for my insomnia. it helped me calm down. it didnt necessarily help me sleep any better, now im back in america and taking a higher dosage of herbal medicine for sleep, the thing about this type of treatment is that its safe, but slow. its not dangerous and quick like taking drugs for sleep. the doctor told me that treatment has to be consistent and that it may take 2-3 months or half a year to show recovery signs and its true, herbs take longer to treat illnesses and conditions. what do you think? have u done acupuncture and found it beneficial for your health? the doctor would insert 10-15 needles each time for helping me with my sleep and there was also a massage therapist. usually you lay there with the needles inside you for 20 minutes but since i have severe insomnia, sometimes i laid there for 30minutes or 35minutes

p.s. i also heard a lady tell me that she also did acupuncture and took herbal medicine to treat her arthritis and it took her a year and a half of consistent treatment for her to get well.and lately, i’ve slept somewhat better!! i dunno if its cause of the herbal medicine or some other reason. but i had serious insomnia for 2yrs.
