alcohol and coffee
I drink both alcohol and coffee. I've drunk coffee since I was five, that's just how I was raised, was with coffee. By the way, you drink coffee in the morning, not at midnight. Definitely not an americano, that's strong stuff.
As for the alcohol, I wouldn't get drunk. Puking isn't fun, and it's bad for your seizures. One beer, a glass of wine, that's fine. So, you can get tipsy, but you can't get drunk. No one really should get drunk, it is so bad for you. But that's culture for you.
I would recommend at least having a beer if people are drinking around you, because people get drunk together. Doing it alone is lonely and probably means you have a problem. Watching people get drunk is lonely because everyone is getting stupid and having fun, and you still have full capacity. Getting drunk with friends though, is really fun. Just face your fear. If you know your'e safe and with people who will take care of you, there's no problem with enjoying a beer or two. Three may be too much. You can't be a designated driver anyway, so pack 'em away.
I only drink socially. Sometimes I think that doctors tell us that we can't have any fun because we have seizures. No drinking, no flashing lights. I mean, what's life without inebriation and flashing lights? My seizures aren't triggered by flashing lights, so I don't worry about it. I love flashing lights.
