I recently wrote on here of my terrible side effects after being changed to Sirdupla. I am now back on Seretide, but the Sirdupla side effects are not completely gone. my lungs are still full of mucus, leg cramps, disturbed sleep, etc. Has anyone else had this problem? I am now on Amxicillin (antibiotic) and Prednisilone (steroid) to try to clear the infection in my chest.
