My puppy has bronchitis please help?

i adopted a puppy about 2 1/2 weeks ago she ended up getting bronchitis at the vets office. Its been a little over a week and she was doing great, she never coughed and now tonight i have been up the past two hours watching her as the coughs non-stop. I thought maybe the cool air was worsening it so i turned the fan off and now shes doing better. Any tips for me shes still taking meds but i cant afford another vet. visit.
