Many people still seem to believe I'm experiencing a effect, but I've noticed that when combining Methadose (Methadone) with Xanax (Alprazolam), it causes me to nod so hard. The reason why it's worth mentioning at all is because, whenever the Xanax has been substituted with an equivalent dosage of any other benzodiazepine - such as Klonopin (Clonazepam), Valium (Diazepam), Dalmane (Flurazepam), Ativan (Lorazepam), etc. - the nodding goes away, and, I've even felt as if I was in withdrawal, which is why I was switched back to the Xanax.
I am aware that Dalmane (Flurazepam) is apparently a partial GABAA modulator, which explains that drug in particular, but what about the others? I still haven't been able to figure out why this is happening. And none of the doctors are able to explain it either.
Eventually, they stopped bothering with trying to switch me to another benzo and have kept me on Xanax. But I hope I'll be able to get off of it some day.
Although I'm not certain of this, it seems likely that nearly 9 years of being on Xanax has seriously messed up my short term memory, and has also contributed to me having issues with erectile dysfunction
P.S. - Another weird thing about my body's response to Xanax is that, even after all this time, it appears that the therapeutic effects have not been lost. In fact, over the past few months, I've noticed that I've been able to regularly skip one of my three daily doses, without any noticeable effects. It's nice because now I have a huge stash of extra Xanax, which is always really good to have around just in case (assuming they don't expire quickly).
