Episode 169: Answering questions then questioning the answers

In episode 169, Mike and James get back to listener questions. Our listeners lead us down the garden path and we end up talking about bladder irritants, riboflavin for migraine prophylaxis, placebo, and as always low doses. Mike rebels by taking a high dose of obecalp which leads to some very strange side effects.
