I tested positive last October. If your chest X-ray comes back negative (and if you have no symptoms it almost certainly will), you will have to take 9 months of INH treatment. I'm taking it right now, and it does stink----I have to go to the clinic every month for refills, INH is lotsa hepatotoxic so I get my liver levels tested every couple of months. No alcohol (I miss my red wine with dinner so much!), no acetominophen, etc. INH inhibits vitamin B6 absorption... when I started birth control (which also inhibits B6 absorption), I got mild peripheral neuropathy in my hands from the deficiency, but after supplementing it went away with no problem. Other than that, though, I've had no other symptoms from the drug. I've actually found it much easier to tolerate than other antibiotics. Take care to watch for signs of liver problems! INH treatment is inconvenient and annoying, and it can be dangerous, but it is usually well-tolerated. Good luck! If you have any other questions, I may be able to help you, since I'm going through it right now and it's all fresh in my mind.
