He was on them last year for the standard 4 months. He found that they made him feel so well that he spoke to the consultant about going back on them. After speaking to specialists it was decided that as long as trough aspergillis tests and lft's ok he could stay on them. He has been back on them since September and the palpitations started about a month ago. We have tested the wall in the lounge with a diy kit that confirmed aspergillis but our landlord suggests we open the windows!!!!
