Benzos Am I going to have withdrawals from this, rotating phenibut and xanax.

[pbuilder]

So I used some xanax and phenibut to ease the transition off hard opiates and poppy tea back onto kratom, usually 5grams twice a day which is a reasonably low dose, but I'm still opiate dependent never the less to the kratom. Prior to this, I haven't touched gabaergic drugs in about 4 months.

I used:
4mg xanax day 1
2mg xanax day 2
2mg xanax day 3
2mg xanax day 4
2 grams of phenibut day 5
4 grams of phenibut day 6
2 grams of phenibut day 7
1mg xanax day 8
.5mg xanax day 9
.5mg xanax day 10 and 600mg phenibut
.5mg xanax day 11 and 550mg phenibut
.5mg xanax day 12 and 500mg phenibut
and today I've taken between .25-.5mg xanax, hard to tell but it was a very small chip off a bar.

I think as long as I keep lowering the xanax dose by tiny amounts (Literally just tiny tiny chips off a quarter of a bar), same with the phenibut which I'm going to try not to take at all today, I should be fine to jump off this all together soon?
Anyone think I'll have anything more then a little rebound anxiety from this regime if I say stop it all together tomorrrow?

Or take like 300mg phenibut tomorrow, and then .25mg xanax the day after, and then stop.
