Hi. After 6months of being on levothyroxine and feeling myself again i am now back to square one with all my previous symptoms and worse muscle weakness. Have new job but off sick with no pay. Just started (6days) taking Jarrow sublingual 5000ug as B12 275 and having bloods done on Friday. I don't think GP will up my 50mcg dose (I self medicated at 75mcg until I ran out) because I'm with in range. The Jarrow is making me feel sick and light headed. I live in surrey can anyone recommend a doctor to see privately to look at me holistically, please pm me. Thank you in advance.
