I stayed in Tokyo 3 months. Had a blast. Make sure you go see Sumo wrestling. Buy the cheap seats and make like an American and sneak up front until you get kicked to the back. It’s totally amazing. The Edo castle is awesome as well. Oh, and try to find a temple having a festival, that’s a fun event as well.
I was in Taiwan and Australia recently. The time change with the diabetes is what kicks my butt every time. I just go on a continuous 1u/hour continuous basal until I’ve been there as many days as time zones as I’ve crossed, then I go back to my normal. Generally, that means about 10 days when you fly over there.
I never even thought to bring along doctor’s notes for my pump and supplies. They all seemed so medically savvy that I didn’t even think they wouldn’t know what they are. I’ve never had trouble getting into countries, although recently I heard someone had trouble getting into Egypt with their pump.
