I've had a box of phenobartial in the cupboard for some time... My neuro let me try it out in an attempt to see if it had any affect on my hppd. At the time, I associated improvement with visuals as the only benchmark for a pill´s worth. They did nothing for my visuals, so I put them in the cupboard and forgot about them.
This week, I am into week 2 of a 3 week break from benzos, to keep my body away from tolerance. Today, I had a massive anxiety attack, one that very nearly had me reaching for the benzos... But I remembered the barbs and took 200mg,,, within 20 mins or so, I felt fine again, good even.
Now, these things are even more addictive and FAR more dangerous then benzos... So I am certainly not recomending them as any kind of long term treatment.... But if you are doing a similiar sort of benzo regieme as I do, or maybe suffer from anxiety attacks but have withdrawn from benzos, it might be worth trying to get a box for any times you get an anxiety attack.
If you suffer from anxiety attacks and want a med, just go for a benzo though. This is purely for the above situations.
