Feeling so helpless and depressed. My injection isn't due until the 23rd January but now, in spite of using Viepatches B12+10 i am quite breathless and no inclination to do anything. Today I wearing 2 patches each containing 1000mcg of methylcobalimin. I keep telling the doctors and medicine reviews man that by the end of 4 weeks the breathlessness is getting bad and I have very little energy. They don't want to listen. 😢 I have got an appointment with a locum doctor tomorrow, one I haven't seen before and honestly I am dreading it in case he is as unsympathetic as the rest. I worry about what he will say if I tell him about the Vie patches. Altogether it's just rubbish at the moment. How many mcg's of b12 is ok to take in daily? I need help so much.
