 [ Symptoms ] since being sick with the norovirus how soon after can you be infected again  i had the norovirus just over a week ago today my husband came home from work gave me a hello how was your day kiss and about an hour later he was sick all of the same symptoms i had he now has my question is how soon after having this can you be sick from it again everything i have read so far about norovirus suggests once it is contracted symptoms begin within 48 hours i am nervous since it is been almost a week and a half that i will contract the virus and be sick all over again [ Disease ] no you definitely should not stop taking chantix varenicline abruptly in fact you would be wise to stop it only under the supervision of a medical professional varenicline is often given to help smokers quit cigarettes usually it is taken for 12 weeks and can be repeated for another 12 weeks if necessary that is a total of about six months since you are at the five month mark i strongly recommend you make an appointment with the prescribing health care provider to make a plan for discontinuing the varenicline at that time your provider also can assess how well the medication worked for you and help you with other smoking cessation support if necessary wishing you well
