My GP said I have asthma and whilst awaiting the chest x ray gave me Ventolin spary.used for 3 day and lost 3 nights sleep on third night very scary experienced all the listed severe allergic reactions very scary after 3 days, took ages to calm down, contacted GP who said the sleep loss was due to ventolin but the other reactions must be a different allergy "and to keep useing it" no way i was experienceing the side effects again... what can this be safely replaced with ?? ... lost faith in my GP to prescribe further sprays
