I had from a viral infection over xmas which made me very poorly indeed. This resulted in my bloods being taken & was then told i had borderline under active with a tsh of 6.8. I was put onto 25mg of levothyroxine & felt great for a wk. i then started to feel very tired. Gained 1/2 st in less than 2 wks, eyelashes & eyebrows started to fall out. Another blood test indicated tsh level @ 2.8 so my med was increased to 50mg (eye/brow lash stopped falling out but not fully grown back) & lost the weight i had gained, felt normal for almost a month until last wk when i needed more sleep during the day again, insomnia during night, aching all over, headaches, cannot loose any weight despite running 3x wk & eating less than 1,500 calories a day-all the typical symptoms. Doc said too soon for blood test & increased med again to 75mg. I have been on this a wk & still feel utterly lousy. I know you will all prob say i need my med increasing again but i am concerned i started off with a borderline tsh reading in january & i am still "within range" now but increased med does not seem to be making a huge difference. A doc friend of mine told me your levels drop gradually over time so am confused. I actually feel much worst since taking levothyroxine & don't know why, i feel like gradually weaning myself off it all together. I want to start trying for another baby this yr (i'm 36 in nov) & can see this slipping away from me. Any advice would be greatly appreciated.
