feeling good

i have just started my new batch of lugol's, this batch was made up by the local chemist, it is a lot darker and was half the price of my first batch on the internet. i am on a bit of a high, is this normal, maybe the first batch was only 2%, this batch is 5%, i find myself smiling alot, which is very strange for me, i am normally very pessimistic, but today i feel positively optimistic. should i take less or stay on my normal dosage? LOL!!!!!!
