ahhhh Keith, detox is fine. You will be fine. I am a veteran of detoxes. lol
They will make you very comfortable. You will eat good. It's really laid back, no big deal. Bring a jacket, they keep it very cold in there. Bring warm jammies. Most people just wear sweats. Bring slippers if you have them. They will probably bring in AA and or NA meetings in there too. I spoke at detox several times about 6 months ago.
The staff is usually very compassionate. They will check your suitcase to make sure you have no drugs. May take away any liquids like shampoos. They are gonna give you meds to ease your withdrawals, You are making a very wise choice. It's gonna be ok I promise.
I kinda enjoyed it! lol It's not like people are walking around going out of their minds or anything. they take your blood pressure regularly. You can watch TV play cards. Best wishes! You will feel hopeful once you get clean and then meetings, meetings, meetings!
