For me it is hard to distinguish between cravings and anxiety.

Can't chime in if it's the medication causing the extreme cravings but at the same time it doesn't sound to far away from how I would of acted when I had cravings kick in. I would be salivating at times just anticipating my next drink. I would wake up and within seconds would already planning my days drinking out in my head. And the sad thing was I convinced myself I wasn't that bad of a drinker all because I could hold down a job and pay bills and I always drank at home.
Cravings are just a normal part of recovery. I couldn't believe after how much of a nightmare hangover I had and the horrible withdrawals I went through that my brain would still be sending me signals to go drink. But by that time I finally had enough and was too disgusted with the damage it caused to myself that it was easier to say no to them. The last real craving I had was around month 4 that hit me pretty strong to the point it was already planning out what I was gonna get after work and that was final. But after a few minutes of reminding my self of what I went through and how far I came it went away. Sometimes my brain likes to remember the good times and starts to romanticize the past but they're fleeting and for every good memory I can think of multiple bad ones that happened.
Just hang in there It's a bumpy ride but the cravings will go away after a while.
