Dear Doctor, All my life (since as far back as I can remember in early childhood) I have struggled with chronic insomnia. I have tried every sorts of pharmacological and non-pharmacological treatment you could imagine, having seen at least seven doctors over 15 years. I have tried everything from zolpidem and similar drugs (no improvement with these drugs) and the benzos (tolerance problems, not good for long term use), to hydroxyzine (ineffective) and trazodone (still cannot sleep and makes me feel ill the next day).
Also I have tried antipsychotics like quetiapine and all sorts of other drugs, and really either they do not work at all, the tolerance issue makes them unsuitable for long term use, or else the side effect profile is too nasty for daily use. I have even been treated with SSRIs and other drugs to rule out underlying anxiety issues. I find myself a very calm person, and my friends know me that way. Also I have been seeing various therapists for years in terms of learning to deal with modifying my lifestyle. I also meditate, practise yoga etc., and only the yoga/stretching helps, but just barely. Finally I was living in Japan for a while where a local psychiatrist put me on etizolam 0.5mg to 2mg per night for sleep. I tried 0.5mg for a few nights without help. 1mg also did nothing. 1.5mg put me to sleep, but I still had this trouble with constantly waking up in the middle of the night as usual. So finally I tried 2mg, and that did the trick. For the first time in my life I could fall asleep at will and stay asleep all night until time to get up, and then not feel all sorts of sleepy/sickly side effects upon awakening. At least in the moment, this has been a wonder drug for me. Now I am back in the United States, so I get my etizolam sent in from abroad. I have been on it for three months at 2mg, sleeping successfully and living a better life, with no tolerance issues. Now, being that it is a benzodiazepine derivative, there is obviously the potential for tolerance. And while I know that with benzodiazepines tolerance is an issue, I also know that the potential for building a tolerance for each benzo depends on the condition being treated. For example my brother takes clonazepam daily for anxiety for years at the same dosage, and while most of the effects have worn off due to tolerance (euphoria, sedation), the anxiolytic effect is as strong as ever and he remains without unbearable anxiety just as well as the day he started. At the same time, if you are looking to "get high" on clonazepam, that effect, you might know, is gone pretty fast. And the anticonvulsant effects only last for a certain amount of time, too. I am sure none of this is new to you, and I only mean to point out that with the benzos the potential for tolerance depends largely on the symptom being treated. Might be a few weeks of good use of clonazepam for seizures, only a few days for getting high, a month for sedation but years for anti-anxiety (making these numbers up, but you see what I mean). And I only put this all here because I am afraid of getting this response that "people build a tolerance to etizolam and so it must not be taken long term." Because the question is to which effect do people build a tolerance, and how quickly, and what percentage of the people, etc. So Iam wondering if there is a strong tolerance effect to etizolam for its anti-anxiety and (in Japan, at least) anti-depressant effect, how does it do for its anti-insomnia abilities? What is the consensus on this matter, and what is your own personal opinion? And has there been any research done on it at all, or is it all based on clinical observation/clinical wisdom? If there have been any studies could you point me to one or two? Have you personally prescribed etizolam for sleep? And if so, have you ever done it for daily use? And is it always, in your case, used only in the short term? And if you have seen patients use it for more than a few weeks/months, was there a point where it just was no longer effective? And how long did it tend to take for it not to be effective anymore? And finally, is it the case that it tends to work quite well for long term use for some patients but not for others, and if so, any idea as to whether it tends to work well that way for more patients or for less? Thank you so much for any help you can give me.
