I had my switch around 250mg
You can see my Baclofen stats here :
http://www.baclofen-forum.com/stats/craving/I am now at 110mg.
My suggestion : Stick with the original dose suggestion. Start with 5mg x 3 times a day - then after 3 days increase by 5mg x 3 times a day - each few days.
day 1 : 3x5
day 2 : 3x5
day 3 : 3x5
day 4 : 3x10
day 5 : 3x10
day 6 : 3x10
day 7 : 3x15
day 8 : 3x15
day 9 : 3x15
day 10 : 3x20
and so on.
With this dose guide in about 2-4 weeks you will start to see first results in drinking less - and then suddenly you will stop drinking on your own - without force needed.
Check out the mywayout forum - it got a lot more information relating Baclofen!
Good luck!
