I'd say keep tapering the ketaman. Suboxone is active in microgram levels. 2mg will be an uncomfortable jump. Possible, but uncomfortable.
I also have a question. Please don't ignore the_ketaman's post though. We both need help. But here is my story: I've been using suboxone daily for 2 years now. I'm prescribed subs for a 2-3 opana 40 a day, or 1-2 B a day habit. Within the 2 years I've been on suboxone, I've been using heroin sporadically. When I began using heroin I was a daily user. I was taking 1-2mg or less of sub in the morning and using my dope at night... That was a daily thing back then (over a year now) And taking a quarter on days without dope. I have successfully been staying away from habitually using all street-acquired opiates for quite a while now, but I still use heroin once or twice a month on average. (with stretches of not using dope for up to 1 or 2 months being pretty regular) I am sober, for the most part. I do not attempt to "abuse" my suboxone when without other opiates for long stretches of time. Heres my deal though: I use around 1-2mg of suboxone, nasally, daily. My symptoms are foggy headedness, grogginess, constant fatigue, occasional nausea, discomfort/disphoria/withdrawal symptoms when using nicotine, be it smoking, using e-cigarettes, or oral tobacco. (and I am a habitual nicotine addict) and occasional depression. I am wondering what I could do to perhaps improve these symptoms? I am wondering if these can be a direct result of daily suboxone use. Am I doing anything seriously wrong that would cause long lasting negative effects on my body/mind by using the suboxone nasally, or taking small, unmeasured amounts? Is my problem that I maybe keep varying the level of bupe in my body without realizing it? I understand the precipitated withdrawal in the days after using dope and going back to subs. Thats fine. But why, when I have stayed away from opiates for a month, or two, and have religiously taken my subs, in small doses, nasally, do I still regularly experience foggy headedness, grogginess, constant fatigue, nausea, anxiety, over-stimulation, depression, etc? I am starting to feel mentally ill. I'm starting to wonder if this sub regiment is permanently messing with the chemicals in my brain, causing a bipolar/mania type disorder. Does taking my suboxone nasally in small amounts greatly increase the bioavailability of the bupe? Am I blowing 1-2mg but truly absorbing what someone using 8mg orally is absorbing? I always wonder if it could possibly all be related to something simple, like dehydration. But I'd like some opinions from you all. Any help would be appreciated greatly. Also, please PM me with any helpful advice on abstaining from dope, or any information on rehab if you'd like. Thanks for any help.
