You have been advised treatment for latent TB infection. You seem to be having nausea
and vomitting associated with drug intake. You need to visit your doctor and probably need to be started on an antacid
medication to be taken empty stomach in the morning following which you can take breakfast after 15 - 20 minutes and after 15 to 20 minutes of breakfast you can take Anti tb medication
. That should give you symptomatic releif. If still no releif then you should visit a Pulmonologist.
