I had high blood pressure when I drank, too. It went back to normal after I got sober. I know that horrible jittery feeling (I used to call it the "inner shakes"). The first several days are the worst. I drank gatorade, took lots of vitamins (especially B vitamins) and didn't let myself get too hungry. Our blood sugar gets messed up on alcohol and when it is low, it feels like a craving.
Of course, everyone's experience is different. Just be safe......
I started feeling better after 3-4 days and it just kept getting better from there. I spent the first couple days glued to this forum and it really helped me deal with the urges to drink.
If we could do it, you can too. Hang in there.....:ghug3
