TSH increases

My TSH levels are a constant struggle for me, and I was wondering if this was normal.  I am taking Levothyroxine, and have been for years, although to my recollection I have never been given any diagnosis other then hypothyroidism.  I recently got copies of the last two years of lab work to review and in regards to my TSH levels found the following:
07/25/05  TSH 5.5  Increased Levothyroxine from 88mcg 100
10/31/05  TSH 5.0
02/13/06  TSH 6.8 Increase to 112mcg
04/11/06  TSH 2.1
12/05/06  TSH 6.3 increase to 125mcg
03/09/07  TSH 5.3 increase to 137mcg
05/01/07  TSH 4.1
I haven't had aother TSH test since 05/01/07, and from what I can tell T3 and T4 have never been tested.  It doesn't seem normal to need to continuously increase medication, I would appreciate any input.

Honestly, I am not an observant person.  When I look at the list of symptoms for hypothyroid, it is me to a T.  I tend to think my TSH levels have not been good for a long enough period of time for me to notice a big difference.  My biggest concerns are my excessive amounts of anxiety, and mood swings (my poor husband and daughter).  Then again, I don't think I have normal energy levels, hair loss is a problem, losing weight is so hard...

It could be that your thyroid is slowly losing all function, and that you have had to increase the dose over time in order to compensate. Just a theory! As someone with no thyroid (TT in July '06), I am on .137mcg.  But how do you FEEL with a TSH of 4.1?  When my TSH was 3.88, I felt the same as I did when it was 2.88.
