I have felt worse since it was reduced from 100 to 75mcg (ages ago, but it took a long time and this forum to make the connection!!)
I'd like to try increasing it back to 100, but would be getting through prescriptions far too fast. Then if it worked, I could go back to the GP and say so.
Is it possible to buy the stuff? Am I breaking rules by asking this question? If so, apologies.
