I wanted to add to the prescription thread: Last summer when I was in the UK, my jet lag was horrible. Like I was delirious with no sleep. I stopped by the pharmacist to grab some melatonin, and they were like kind of offended that I asked without a prescription. So on my next visit, I brought huge bottles of all my common meds (ibuprofen, benadryl, melatonin) and kept them at my husbands for next time. Target's generic brand is awesome!
