I would pick Kratom over phenibut. The latter has too many horror stories attached to it. But neither one is ideal. The kick from poppy tea sucks but it'll be over in a week. I would hit it with traditional benzos.
Strange many people who I know have used like poppy seed tea tell that they get even 3 months of WD's. One guy told that the WD's were just as worse like from heroin or oxys but lasted 2 months.
For me 2 year of daily use high doses of it, gave 1 month, after that still got some lesser WD's
Now I kicked 4 month of use where I dosed very often (every 2 hours in the last month every 1 hour), very high doses. Now 1 month is gone and its over already, I think wd's went away after 2 weeks.
So it all depends on how long you have used, 2 years, one month, 4 months, 2 weeks. This last time I first time got nausea from opioid WD. in past Ive quited 2 month of very heavy use of tramadol (first month used 2g, second sticked to daily 1g, always used valium), I quited 1 month of heavy use of tramadol around 4 times and one time 2 months, I quited most of the times could turkey, once used pregabalin for only 2 days (didnt have much of it), one time I used buprenorphine for 3 days to take tramadol wds off and no wds at all after that. The last time when I used tramadol because I was using poppy seed tea daily for 1 year already, and then couldn't get any opioid beside codeine and tramadol. I used 1,5g tramadol but still felt like shit, I this time I didn't use valium like the last times, but gabapentin for preventing seizures (as its used as epileptic medicine), I took 3,5 gabapentin every day, but I still got seizure. After that I went back to poppy seed tea when I came back- Tramadol use was all happening in Thailand.
I seem to have very quick metabolism for poppy products, because most addicts tell they take drink it only 3 times a day, but I used 17 times a day, before bed I always took big dose, but I always waked up after 4 hours in mild WD's.
Thanks to my quick metabolism, I've never had long WD's, tramadol wd's went away in 1 week, and 2 years of poppy tea Wd's went away in 1 month, after that 4 month use WD's went away in 2 weeks, but it was most intense WD I've got first week was all puking, didn't have any appetite even with things like pregabalin or GBL that normally makes you eat much. Also I felt so week that just walking 10m was so hard. I felt shit even when I was taking lisdexamphetamine, gbl, benzos, and pregabalin all the same time. Second week I already felt better, 3rd week I didn't felt any wd's even when sober, this is 4 week and after day of high dose of pregabalin I felt good.
Note that I never went cold turkey on poppy tea, when I quit 2 year use I remember one day when I was waking up and no drugs on my system, I felt like I was burning inside and outside, no position was good, it felt really like somebody was torturing me with nastiest ways, I had only phenibut left, so I took it little by little, first 2g, then 2g, then 2g, I waited it to work and it was horrible, 1 second felt like 1 hour, phenibut will start to work very, very slowly, like 5 hours, after taken 10g and phenibut fully working I felt like living again I felt great. Also notice that on that quitting, when using GBL I still felt terrible on body but great on mind. gabapentin helped also but still felt like my body was tortured little and that was 4rd week. After that hell I still was stupid enough to think that taking some other opiodi once month is not causing any problems, I always got 1 week WD's not so nasty, I could manage them could turkey, I continued that route, but I thought maybe 2 months break and then using one day wont give WDs', I was wrong every time. Then I had 3 month break and tried again once, still got WD's. After 4 month I tried poppy tea again, and this time I got mild wd's for 1 month, but went through them could turkey. Well then I thought I take poppuy tea for 4 days and then use pregabaling for wd's would help, it did work, but after 5 day binge one poppy I made decision that no more opioids anymore, so this time I pregablin on doses 600--3000mg for 2 month. Hot HORRRIBLE NASTY wd's like from poppy, methylphenidate took them all away. Well I ended up using poppy tea for pregabalin wd's, it took all WD's away. So now I'm here again quited opioids for good, I hate them I never will use any opioid again, never, I don't have even any kind of craving for any opioid, I wouldn't take oxy even if I got it free. Well after this week I stop using all these drugs that I used for wd's. I changed them constantly, so I didn't get any wd's when my 10day GBL ended. Now I take speed 2-3 days then pregabalin for 2 days, then speed. But speed is too hard for mind and body and makes me just doing really nothing but write on forums and listening music, and for 3 first weeks.
Well I know it will be hard to go totally sober after this week, but I much or I end up addicted to amphetamines totally.
