I hate drinking

I abhor it. But sometimes, because of a culture where if you don’t drink, you’re being disrespectful, my friends force me to because of “Respeto.” And honestly this isn’t just for friends, this also applies to professional meetings and get togethers where you’re forced to drink otherwise you’re being disrespectful to your co-workers and colleagues. So, beloved medical practitioners of r/philippines, I was thinking, can I get a doctor to sign a certificate or make a diagnosis which basically bars me from drinking, just so I have a medical reason to not drink?
