I have only gone when I had really bad colds. They prescribed medication (although they don't actually give you a prescription, they sell their own medicine. Even if you ask for a prescription, they will not give it to you). They recommend 2-3 shots every time I go then ask to come back the following day for more (but I never go back b/c I'm already feeling better by the following day). Not sure if the shots make a big difference, I have always gotten them, but I do get better right away. With consultation fee and medication I usually spend about $120 total.
