I am in the 13th week of the 24 week Sovaldi / Ribavarin regimen and I am experiencing confusion and trouble concentrating during study periods. I'm a 4th year student and this usually occurs when I'm reading or taking in new material. It's taking me two to three times longer than the other students in my Applied Behavior Analysis course. I sometimes have to re-read material several times to understand. Never had this problem before; I'm falling further behind and starting to worry about my gpa. thank you for any feedback of conversation about this.
