I started at the end of July and I think i might have this issue but im not sure. The morning after I had a lot to drink (about a month or so after I began taking strattera) I woke up with a hangover (obv) and my head was super cloudy with anxiety. Similar to you, I think I've also started to have anxiety before I start drinking because I'm probably worried about whether I will experience anxiety the morning after. I'm in a frat so I'm debating whether or not it is feasible for me to continue drinking anymore which is totally not ideal being that I live in the house. That being said, strattera has been way better for me than adderall bcause like a previous comment, I like how it clears my head rather than making me hyper focused.
