Flualprazolam kindling

About 2 years ago, I had a somewhat major benzo habit. Dosed about every other day, dont remember from on or off days, taking about 6 mg of what I thought to be alprazolam, but who knows. I was tripping nuts and had a seizure, some have said bunk acid, some have said benzo withdrawals. Aside from (potentially) this, I never felt substantial benzo withdrawals. Just the usual grogginess and anger the following day or two. This phase lasted about 4 months. After stopping for a few months, I moved away for school and was taking xanax about two times a week, but at stupid doses (at least 6mg, at most 20mg, usually all at once). Again, I did not experience any substantial withdrawals. This phase lasted about 6 months. I had one more benzo phase, lasting about a month or two. I would take around 6-10mg,again always all at once, and not throughout the day. Again, never any withdrawals aside from previously stated. I have not had a benzo in about 3 months. However, I was wanting to try flualprazolam this weekend. It would be a one time ordeal, as that is all I will have enough for, and I cannot order these things to my house. The dose will start small and rise until desired effects.

1. Will a one time use after months of being clean potentially cause withdrawals? Or just the usual benzo hangover I have described above?
2. I have read about "flu" prefixed benzos causing seizures while on them. Not withdrawing but while on them. Is there truth to this, particularly regarding flualprazolam?

Edit: I have decided against it. I have been clean from benzos for 3 months. There is no need to potentially rekindle as destructive a habit as benzos for the sake of having fun for a night. Knowing me, I would wake up semi rekt the next day and take more. Since I got clean, I started a company with my dad, am making better money than I ever did before, and don't spend it all on bars, bud, and bitches. Just bud and bitches now. One night of blacked out fun has sent my life spiraling before.
