Following from your previous thread, here's a suggestion on how to do a crossover if you choose to proceed with it. So first let me explain what I'm thinking. I don't know how to calculate the 0.4mg's and I think it will be difficult to compensate/adjust for that in Valium. If you use the
calculator to do equivalencies, you get 2.2mg Xanax = 33mg Valium. So lets round that to 35mg.
Now if you look at this crossover table:
https://benzo.org.uk/manual/bzsched.htm#s7 you'll see each 1mg Xanax has been replaced by 10mg Valium except for the evening dose where the 1mg has been replaced by 20mg Valium (Stage 11 when crossover is completed). So your day doses are half of that and I'm thinking we half the Valium for all the day doses, and keep the evening the same as your evening dose is also the same. In the end you'll end up with 5mg, 5mg, 5mg, 20mg which combined is 35mg. This brings us close to the 33mg calculation.
Start:
0.5mg 0.5mg 0.5mg 1mg
Stage 1:
0.5mg 0.5mg 0.5mg 0.5mg
10mg V
Stage 2:
0.5mg 0.25mg 0.5mg 0.5mg
5mg 10mg V
Stage 3:
0.25mg 0.25mg 0.5mg 0.5mg
5mg 5mg 10mg V
Stage 4:
0.25mg 0.25mg 0.25mg 0.5mg
5mg 5mg 5mg 10mg V
Stage 5:
0.25mg 0.25mg 0.25mg Stop X
5mg 5mg 5mg 20mg V
Stage 6:
0.25mg Stop X 0.25mg
5mg 5mg 5mg 20mg V
Stage 7:
Stop X 0.25mg
5mg 5mg 5mg 20mg V
Stage 8:
Stop X
5mg 5mg 5mg 20mg V
From this point you are equivalent to Stage 14 on the schedule I linked.
Where I've written 0.5mg Xanax, you'll take your current 0.4mg dose. I just used 0.5mg in this schedule for easy comparison to the Ashton schedule. Please have a look and see if this makes sense to you?
