That's not how it worked for me.
I was put on a script that - as i tapered down - i was told to dose either a couple of times a day or once a day.
The specialised addiction therapy doctor that i helped me through it told me it made no difference to my physical safety (ie seizure risk).
I tried various approaches over the course of the taper - and found that with diazepam, it made no difference.
As for withdrawals - i went from taking ~1 gram of flubromazolam every couple of months (a very potent benzo much stronger than even alprazolam - i shudder to think what my daily dosages got up to - i had a monster tolerance, but also spent a lot of time blacked-out) to a rapidly declining diazepam taper - and to be perfectly honest, i don't know what typical "benzo withdrawal" even feels like.
The seizure/hospital thing was a whole other story. But unlike opiate withdrawal - a very familiar sensation to me, as a long-time nuser - i can honestly say i'm not experiencing benzo withdrawals (the taper i did was almost a year ago) and when i ceased dosing, i experienced no discomfort whatsoever.
I have a great doctor and detox service - which are free in Australia, so there is no reason not to seek something like that out, mr mushroom, assuming you're still in australia
Now, everyone's metabolism is different, much like our psychological make-up and reasons for using.
But dosing once a day was
no problem for me.
I'm not in withdrawal - and besides a bit of insomnia, and dilated pupils throughout the taper - i really had no wd synptoms to speak of (when undergoing a medically supervised taper).
I don't know the specifics - or relevance in tapering - of drug half-lives or "clinical effects"; which is why i recommend people seek professional medical assistance in coming off benzos. It's something you need to take seriously, and being helped by well trained and informed people is the most sensible way to do this, rather than trusting what you or i or anyone from an internet discussion board have to say on the matter.
I fell into a benzo habit after coming off opiates, so it was really just a matter of physical safety for me. The rebound anxiety and whatnot was of little concern to me, compared to having seizures, psychosis and the other nightmarish stuff that happened when i fucked up prior to this.
So, like i say - we're all different. But don't take my word for it - a doctor supervised taper is really the best option in my opinion.
