Im sorry too say this but Ive had a nightmare de-tox once I couldnt walk properly was seeing things shaking, panics attacks racing heart constantly but it all disappeared after 3 days. Then comes the hard bit staying sober, alot harder than de-toxing as have found out. Things get better though so dont take what I said as what yours is gonna be like that was just me I was drinking bout 2 litres of vodka a day. All depends on how much you drink the few days just before you go in there keep it too a minimum will make the de-tox so much easier on yourself.
