Level, you do need to see your doctor and have him run current tests on blood pressure or whatever, so that he can properly prescribe meds for you.
As to not drinking ANYMORE EVER, it may be a lofty goal. It's a good one, but I can tell you that, as an alcoholic, my goal is to refrain from alcohol TODAY. Tomorrow, I hope to have that same goal again, and again the next day, and so on. But to just say "now I am determined not to touch the bottle again" when you have touched it within the last half day of saying that- it's a goal where you are almost predicting your failure.
I was already sober for a long time when I learned TTATT and I also fell off the sobriety wagon at that time. So, I didn't reach my goal to refrain from alcohol several times. But then another morning came and I set my goal again to stay sober THAT DAY, and I have done so for each day since that day. Instead of lofty goals of years or "forever," I plan to stay sober today as I have done so for maybe 10 years now.
And that is not a sell-out, so I can fail and start again. Each daily goal has been important to me. I know that one day's failure could lead down the path of not setting that goal ever again. But I hope that is not the case. Just in case, I better try hard to stay sober today.
Be fully honest with a doctor. If you were only sober for a day or a week, tell him. If you won't take your meds or won't do what the doctor wants you to do, tell him. It's your money or your insurance paying him to help you the best he can to keep you alive under the conditions that you will abide by. Don't hide a "drinking problem" from him and don't skip seeing him because you haven't stayed away from drink.
