you are already on the road to recovery even tho you may not realize it. when we admit we have a problem with alcohol it is the first step. i am a recovering alcoholic and bipolar. it is not uncommon for both to occur to the same person. we medicate our bipolar with alcohol and for a while it seems to help. trouble is it's not a good mix since our moods are already unstable and alcohol is a depressant. i can totally relate to it stopping the mind from racing.
the most important thing i am want to share with you is sobriety enabled me to get my bipolar stabilized and on to a wonderful quality of life. both conditions should be treated simultaneously to asssure you the best success. you are doing just that with your plan. the rest will take care of itself if you get treated for both, follow your medication plan for the bipolar, and stay sober. IMHO, a 12 step program of recovery can help you with the support system you need and staying away from a drink.
my life now is far better than i could have imagined due to treating these illnesses. i hope that i am giving you hope for your future. your honesty is a good sign for the outcome of your efforts. keep us posted.
