my thinking is very sluggish

[Svet]

I am on levoxil now for a year. All of a sudden, my thinking gets back to where I had started a year ago: very sluggish, can not think straight, very hard time concentrating. Could it be a need to be tested for right dosage? My doctor recommended next blood check in may 07.
And there is a definate almost "cold" or " cloudy" feeling right in my forehead. What is going on with me, what should I do?

Ask your doctor to check your calcium levels.  I have been going throught this and have had a very difficult time concentrating.  Finally getting the calcium leveled off, feeling somewhat better.

Have new blood check - you said May 07...you're late?  Sounds like your meds need to be raised - maybe keep your TSH around 1.0.  Doc usually takes into consideration how you feel and blood tests combined.  Good luck.
