Hi Paulene and welcome to SR.
Congratulations on your sober time!! That is awesome and inspiring, and I hope to one day have that much sobriety under my belt. Thank you for coming here and sharing with us.
I absolutely do not think you need to restart your sobriety date because of medications!! As for the wine at the wedding, that's up to you. If you didn't get drunk, if you stopped to prevent things from getting out of hand, and it didn't cause you any problems afterwards, I'd vote in favor of not counting it and chalking it up to a close call.
You say you're a "people pleaser"... the only person you have to "please" in this situation is YOURSELF.
My only personal experience with this is that I do not count medication (or mouthwash or orange juice or vanilla extract) against my sober time. It is being used in its intended purpose and in the recommended amounts so I am not doing anything wrong. I hope you still find my opinion helpful even though you only asked for stories of experience.
Best,
TSH
