My GP reluctantly agreed to let me follow Dr Skinner's dosage instructions providing I had a blood test after 4 weeks. I've had the test and have to see him tomorrow to review. I was due to increase to 75mcg yesterday and am a bit worried that my GP might not agree with this. Can anyone give me any advice on how to tackle this? I can't say I feel any better or any worse on Levo up to now. As Dr S doesn't appear to respond to phone calls I feel like I'm on my own and am a bit worried things might start going wrong, as people always seem to really rate Dr S's methods but I may not be allowed to increase my meds. But on the other hand, I'm not sure whether I need to!! Help!
