Since you had been precribed macrobid
, I take it that you had been diagnosed with urinary tract infection
. Also you have not mentioned what urinary symptoms you get on smoking
. I would like you to know that smoking is well known to increase one's risk of developing bladder cancer
and other urinary problems. So quitting should definitely be on your agenda. Also get yourself evaluated for persistent infection when you see a doctor and ask for a change in prescription as some other antibiotics may suit you better.
