I was diagnosed with high TSH levels about 10 years ago, & as I wasn`t showing any obvious signs of hypothyroidism, my gp decided just to moniter me &see what happened. Recently I was found to have raised cholesteral, & I tried statins, which made me so tired that I slept most of the time, so I stopped taking them. Diet hasn`t helped my cholesteral either, so a month ago my gp prescribed Levothiroxine 25 in the hope my choleseral is caused by low thyroid function. I`m due to get my TSH levels tested in 3 weeks time, & cholesteral in a few more months. I`m wondering if others on this site have had any benefit from taking this dosage, as I don`t feel any different yet.
