Hey alfers.:)
I am sorry that you are not feeling well at the moment...but it is good at least that you have figured out the connection as to why.
It is known that alcohol renders A/D meds less effective, and also can increase the alcohol's effect on the body...so you have a lose, lose situation when you are imbibing.
In other words...you may have a hangover...and not have your meds helping you when you feel bad and need them most!
Perhaps you may want to stick to just one drink, or even a mostly seltzer water cocktail, like a spritzer in the future.
I hope that you start to feel better really soon, and get back to feeling well again. I am glad that otherwise, the Prozac is helping! Good news.:)
Keep posting!
