Menchi is right that you need to give the meds more time to determine results.  The half life of a T4 med is about one week, so it takes 4 weeks for the meds to build up to over 90 % of final effect in the blood.  That is why doctors typically don't want to re-test any time sooner than 6-8 weeks.

More importantly, you need additional testing beyond TSH.  TSH is a pituitary hormone that is affected by so many variables that it is inadequate as a sole diagnostic for thyroid.  At best it is an indicator, to be considered along with more important indicators, which are symptoms, and also the levels of the biologically active thyroid hormones, Free T3 and  Free T4.  FT3 is the most important test to know because FT3 largely regulates metabolism and many other body functions.  FT3 has also been shown to correlate best with hypo symptoms.  

A good thyroid doctor will treat a patient clinically, by testing and adjusting FT3 and FT4 as necessary to relieve symptoms, without being constrained by resultant TSH levels.  symptom relief should be all important, not test results.  Tests are valuable mainly as indicators during diagnosis and then to monitor thyroid hormone levels as medication is increased toward symptom relief.  

I think you will  find this link helpful in understanding the benefits of clinical treatment rather than being treated by TSH level.  This link is to a letter written by a good thyroid doctor for patients that he is consulting with from a distance.  It is written to the primary care doctor of the patient, to help guide treatment.

As far as i'm aware there's no specific dose for specific results. I'd give the tablets a little longer to do their thing. Look up the symptoms of hyperthyroidism as that would be the same as taking too much. I doubt it is that after only 5 days on it though. Everyone is different i guess.
