I know this is bit outdated post, but I'm just gonna report my case.
When I first started taking tramadol, as an opioid naive person, I felt nothing from 100mg of zendol-sr tab. So I decided to double the dose. I usually take tramadol on 7:00, before I go to work; before or after the meal. I start to feel something after 8:00, bit energetic, yet euphoria has not reached its peak. In this point, you may feel like you're on stimulants. After 3hrs pass after the dose, you start to feel euphoria and stimulation. you take lunch and it may taste like shit when you're stimulant naive(All sort of amphetamines like; phentermine, phendimetrazine, phenmetrazine, epinephrine, etc.). However, smoking pot on it usually solves the problem. but after the meal, you most likely to feel nauseous on about 13:30 or 14:00(T+6:00~7:00) which means its peak has just reached. Taking a nap(which is hard without other substances like pot, benzos, soma etc. so I usually smoked pot or took one or two soma sometimes w/ xanax )or glass of milk is recommended. About one hour pass since the nausea begin, you feel the perfect part of this drug. Nausea is gone,(but might feel long headache from this point until the drug completely comes down) and euphoria slowly decreases from its peak for about 3 more hours, personally, it has been best moment for me so far. Though itchiness and fever-like symptoms starts to occur too, you'll be fine taking one or two DPH 25mg tabs(sold as sleep-aid OTC) or any other antihistamine of your choice. The drug completely settles down on about T+12:00, and the pleasant point IMO is T+2:00~5:00(more speed-like point) and T+7:00~T+10:00. Also, after building some tolerance to opioids, you'll find yourself going through higher doses without vomiting. First&Second time was worst IME, so don't easily give up on this uncontrolled gold very soon at your first week on Tramadol.
Plus, SR version seems to produce less side-effects than immediate release version. But since the onset is slow and the high is too long, you won't find it very hard to dose at the exact moment when you need it. But when you're OK to be under influence all along during working/at the school, for a recreational purpose, choose SR. Otherwise, when you just want to enjoy the night, take IR.
Tramadol-SR experience in chronological order:
T+0:00 take the pills.(Consider your weigh and tolerance for dosage, check out my example at the bottom)
T+1:00 start to feel bouncy and energetic. no side effects yet. Might feel thirsty at this point.
T+2:00 euphoria comes and feel like on speed. music starts sound better and anxiety goes away.
T+6:00~T+7:00 start to feel nauseous, especially when you took a meal. Headache and jitterish feeling lasts for less than an one hour, depending on individual's tolerance or system.(More tolerace, shorter and milder)
T+7:00 After the worst part of the trip is gone, euphoria is at on its peak and music sounds wonderful. It's like on DXM or MDMA with more hypnotic and numb, noddy feeling than energetic feeling. Enjoy this moment with your favorite activity. You can dance, listen to music, watch TV, or play video games.
T+10:00~T+12:00(depends on individuals and how many activities done) Start to feel like 'when will this high fucking end wtf' and at one point you realize that high was gradually decreasing time by time and that high has just finished. You feel tired and headache, nausea might strike you again. Tremor or cold sweat might accompany.
Also, at the vulnerable moment, nausea and headache seems to be magnified and provoked by smoking a cigarette or two. Which is why you should be careful because while under influence of Tramadol, many people crave smoking cigarette more than usual. It might seem to potentiate your high but it's ridiculous. All it does is increase the side-effects. I'd rather take 50mg or 100mg more for better experience. Tobacco is not recommended on the trip.
<Dosage model of Tramadol-SR>
tolerance naive, around 150lb:
100~150mg
tolerance naive, around 200lb or more:
150~200mg
little tolerance, around 150:
150~200mg
little tolerance, around 200 or more: 150~300mg
high tolerance, around 150:
200~400mg
high tolerance, around 200:
200~400mg
do not exceed 400mg dose daily. And in order to put up seizure threshold, taking benzos together will work nicely. Valium is mostly preferred, as its half time is long enough and slightly more euphoric than Xanax.
One last thing: this is recreational report of Tramadol SR. Medical dosage should be set by your physician, not by your laptop internet pharmacies.
Have a nice trip!
