Just curious if using it over time will cause liver/stomach problems.

I've been taking 2 tablets every night since my headache got worse on Monday after the sudden stop in the taxi. No more taxis or even vehicles of any kind for a while. Well under max dosage a day...

Which leads to a side question: Do any of you avoid rides from even friends or family knowing there's a risk of a sudden stop?

Do you avoid vehicles completely?

Thanks for any info!
