Self-Medicating with Alprazolam after GHB addiction

[KaizenLifeImprove]

So here is the story.. SWIM has been GHB user for more then 1.5 year, 90% of the time 24/7. A month ago things totally spun out of control and he went into heavy rehab, on his own, supported with phenibut and xanax and slowly but surely getting back to normal (started 3wks ago). He almost hits 10 days of totally being clean now, but still uses the xanax daily.. on which he has some questions.

Now SWIMs doc knows his GHB addiction for months already. He sort of has a deal with the doc that he gets 2mg a day for sleep. So far SWIM has taken this subscription 3 times (45mg / time) every month. SWIM hasnt used all of the xanax, he has 65mg left.

Today SWIM was worried he might be 'addicted' to Xanax because he takes 1x .5mg & 1x .25/.5 per day to feel relaxed & ok to function. But to his 'relieve' this seems like a light dose when I look at recommended dosage for Anxiety Disorder. Btw this is no doc advise, SWIM does it on his own 'feel'.

Now then, SWIM wanted to goto the doc and take himself of the subscription and ask for a Valium taper program. But he now doubts if that's a wise thing to do. SWIM does not want to have benzo's long in his body. When he wants to use Benzo's he wants them to work quick, effective and not too long. Xanax seems perfect for that.

After this story SWIM has 2 questions:
The Valium subscription is not needed for 'tapering' purpose right, and SWIM better be off not fooling around with too long working benzo's?
When should SWIM look out with self-medicating with Xanax, what dosage levels / usage times&frequencies?

Bonus question: Would SWIY get another 45mg subscription of Xanax (Doc thinks SWIM took 1mg/day last month instead of 2mg/day) and then stop subscription?
