Have been feeling tired and low energy ( thought it could have been dehydration from kick starting exercise on August 1st) so when the nurse called me in for blood pressure check, I asked for a blood test ( had low b12 a few years ago and was prescribed tablets- hardly eat any meat). TSH is 5.94 and I've been prescribed 50mg levo. Is this right? Should I not start on 25mg, esp as only just over the range. Day 2 and I feel like I have a reduced appetite. If I lose weight, all well and good as I've put on 2 stone in last couple years and finding it hard to shift. But I hate taking tablets and wonder if I should research alternative therapy / herbal or natural medicine like sea kelp/selenium. I don't mind taking levo for a few weeks if i have to. Is it likely that when I go back for my blood test in 4 weeks and if tsh is normal that I will come off levo altogether? Not happy about being on it for life. If that's the case, I'll take it for a few weeks then try alternative meds and come off the levo myself. Worried that the levo will weaken my thyroid altogether or make it sleepy and then cause other problems in the body. Also, shouldn't I have something for the b12 too? That seems low to me. I asked the surgery and they said doc needs to think about prescribing me anything for the b12. Any advice appreciated!
