In my personal experience, I can contribute some advise that might be helpful to you.
Starting off, I know that opiate WD and kratom WD don't compare under the same degree of suffering and discomfort. In ways, they have their similarities though.
*Don't let my mention of kratom defer you from this post*
I use to be a heavy using opiate addict, and know what the WD's are like from opiates - They are awful!
I am now a current kratom user, and kratom has helped me so much, by muting my craving for prescription opiates.
The last time I used any type of opiate was the other day, only because a can of butane exploded near me and I received some really bad burns.
My mom had a leftover bottle of Tylenol 3 w/ codeine and I took five, so I could go to sleep, and still have leftover pills that I haven't thought about
touching since that first night. But, I still have my kratom, so I just use that daily. I could care less about the leftover T3's.
Let me digress:
When I use to go through opiate withdrawal, and whenever I take kratom vacations - cold turkey - I use to go buy the Day/Night time DM cold medicine jell capsules from the super market.
Unfortunately, they put more day time jell capsules in the pack, than they do the night time caps. The DXM and acetaminophen in the cold capsules really helped take an edge off of the WD's.
The night time caps were way more self valued, in my opinion. I would normally take one (two if necessary) and I would take melatonin that was made with 5-htp added by the manufacturer,
and that combination really helped me get a full night's sleep 90% of the nights I would go to bed.
Keep in mind, everybody is different, our bodies are different, and we are all different mentally (mind over matter).
This option in supplements I'm throwing out here are based on my own personal experience, and I'm not advising them as a cure-all.
I'm just letting you know what worked for me, to dull my past experiences of WD in both opiates and kratom.
Eat healthy. Get some sun. Drink fluids - Pedialyte was great for me. Exercise, if possible - even a quarter mile walk a day has a huge impact on getting through physical WD. And for me, most importantly, find a way to stay busy.
I know that in WD, the majority of people don't have the energy or the interest to do anything; many people become bed-bound through WD, and will lay there throughout the day focused
on how good it would feel to go score again, or they lay there with nothing to occupy their mind, and in doing so, it gives their brain nothing but time to focus on the depression, anxiety, pain, and cravings.
Anyway, I hope my words helped. I hope that you can get through this as painlessly, and quickly as possible.
God bless you, and good luck!
