Sorry for your troubles. Considering your age and the length of time on the benzo, it is extremely hard for the brain to adjust to lowering/discontinuing a drug your brain has been bathed in for so long - the structures (receptors) in your brain have been changed, and are slow to change back to pre-benzo, if they ever do. I say this as a 62 year old with a similar benzo history. Clearly your psychiatrist will disagree with me, and I don´t want to go against doctors advise, but maybe consider and discuss with your doctor the probability that this (4 month?) taper was way too fast. That´s pretty common for psychiatrists to do, who lack and understanding of the effect of long term benzos on the mature brain, or any brain. They seem to have this formula that consists of taking away large percentages of the drug at a time - just, no. Consider a much slower taper if you are determined to discontinue, you´ve got to do it right this time, as multiple tapers and reinstatements can result in kindling, a neurological condition resulting from repeated withdrawals, seizure possibility heightened. You may have to think of your taper in terms of years rather than months. I did, and I still wasn´t able to come off completely; I hope you do better than I did, but in my opinion you´ve got to slow it way WAY down. Hereś an article that explains all this better than I can, and suggests cutting not more than 5-10% of currrent dose and holding for several weeks at a time. Some need to go even slower, 2-5% and hold for several weeks.https://www.benzoinfo.com/benzodiazepine-tapering-strategies/ Best ~
