I have been taking Zoloft for about 6 months now. I am consulting with my psychologist and I am going to stop the medicine. My question is: I haven't taken it for 4 days now, should I start taking it again and taper off of it or just wait out the withdrawal symptoms, which started yesterday?

I've been taking this branded medicine for my migraine and it costs 28 pesos. I onced asked the pharmacist if there is a generic equivalent and she gave something that costs only 8 pesos. It worked fine for me.

My question is:

Having spent a fair bit of time reading the various evolution/creationism questions and answers I see that, for the most part, the people on the pro-evolution side understand what the theory means and explain it fairly well.

But there are common mistakes, logical errors, and misstatements made all the time by creationists to defend their view of things. While some of these might be considered judgement calls, the ones below are not. Yet they recur at such a dramatic rate that I wonder about the cognitive skills of the people who perpetuate them. A few examples of errors made in defending creationism.

1. "Evolution is just a theory." How many times do people have to be told that a "theory" is not the same as a "scientific theory?" They are not the same words. So basing any arguments on what "theory" means outside of science proves nothing more than a lack of understanding.

to be continued...
