Thyroxine tablets symptoms and conditions

Hi, I was taking Yasmin for around 3 years when I started becoming really tired and lost half my hair among other symptoms. I went of BCP all together and read up my symptoms on the net as I suspected my thyroid was under active - sure enough TSH levels were too high but T3 and T4 levels came back normal - was put on 50mcg of thyroxine but because I was still symptomatic this was upped to 100mcg, I have since discovered I also have multiple nodules on my thyroid. 18 months later my doctor talked me into getting a Depo Provera Injection and in the last 9 weeks since I had it I have never felt so ill in my life. Night Sweats, fever, swollen glands, nausea, sore throat just to name a few. I have had to halve the thyroxine tablets and I am still feeling lousy. I am seeing a throat specialist this afternoon. Wish me luck. N.
