Hi all . Have now been taking Ruxolitinib for four weeks and have noticed my concentration is improving , my rash has gone and the itching is not so bad . On the downside the headaches and dizziness are worse , have fallen a few times and with osteoporosis its quite worrying . Tiredness is about the same and shortness of breath worse , but what I'd like to ask of anyone on Rux is has it made you dream more . The past few nights have been very scary for me and last night I even left a light on . Have not done that since I was a kid. Getting scared to go to sleep even now . My appetite is no better either and was really hoping Rux would help with that as at 50kg I can't afford to lose anymore , but its the increased dreaming / nightmares that's really bothering me .
