** Dear Thanks for contacting with your health concern 1. As you are already a diagnosed case and was under the supervision of your Physician and now with a Pulmonologist opinion thus he must have given due consideration in changing the dose from 4 to 3 drugs and also with the timing. 2. since you are taking medicine for lymph node TB which comes under Category III for which total duration of taking ATT [anti tuberculous therapy] is 8 months according to WHO guidelines and 6 months according to treatment regimen followed in India under revised National Tuberculosis control programme [RNTCP 1997]. PS. lymph node TB is a less severe form of extrapulmonary tuberculosis 3. dosage of medication differs from doctor to doctor since some prefer giving the dose depending upon the category of TB and some prefer it weight wise. 4. look out for any co existing disease particularly AIDS [check with HIV test] since association of HIV and TB infection is a serious problem and can make latent TB overt PS. also check with haemoglobin and blood sugar level, liver function test regularly 5. as far as changing the timing of your dose is concerned it will be best reviewed by your prescribing physician, your primary care doctor or pharmacist, although with Rcincex [rifampicin/isoniazid] it is best to take them on empty stomach which helps the body absorbs more drug while ethambutol can be taken after food, but speak with your doctor about your question 6. also take/make good, nutritious, protein rich diet and avoid oily and fried foods
