The "looking forward to them" thing is worrying, Tan. And the "thinking a lot about them."
After I last drank I had the worst panic attack I have had for years, I thought I was gonna have to go to the ER or something, I thought I was gonna crack up.
I forced myself to not think, I lay down and put on an Eckhart Tolle audio thing that I find relaxing and emptied my mind as much as possible, I think the fact that I have been meditating on and off for a while helped me do that.
I would strongly recommend meditation/mindfulness training whether you decided to keep taking the pills or not.
Whether or not you should keep taking them, I really can't say. I hope you can get some relief from the anxiety as I know how horrible it is.
