I recently bought some Tianeptine. I've got about 20g of the stuff.
The first time I took it, I went a bit overboard and did about 300mg. It wasn't opiod-like (though I've never done opiates), or MDMA-like euphoria at all, it was mostly just energetic anxiolysis, like the first time you take a large dose of Phenibut, actually.
After about 3 days (lowered dose to 100mg max), the effects seemed to stop altogether.
I theorized that since it enhances uptake of 5-HT, then maybe I've depleted my 5-HT? So I bought some 100mg 5-HTP pills, and started taking 3 at a time about 3 times a day, while taking no Tianeptine.
I took 100mg Tianeptine again after a few days, and it wasn't as good as the first time, but it was better. However, after about 3 hours I got very hot a nauseas, and started vomiting for about 5 minutes - just clear liquid vomit. It felt like mild serotonin syndrome, and I was pretty panicked at that point, but after vomiting I felt 100% better, but the 'high' from the drug was completely gone too, maybe the vomiting and the nausea just killed my mood.
I kept experimenting with 5-HTP and Tianeptine for the next few days, adjusting doses and times taken between the 5-HTP and Tianeptine, but each time I found that it ended up in nausea and vomiting. The last time (2 days ago), the nausea didn't subside after vomiting and kept going for a few hours, and I kept vomiting for quite a while. I did that day take a large dose of Phenibut too, which may have had something to do with it, but anyway it wasn't nice.
I also thought of taking some Venlafaxine for a couple of nights in a row to inhibit reuptake, thereby increasing the 5-HT in my brain, for the Tianeptine to use up later, right? IAmNotANeurochemist so this is all just total guessing on my part, but it made a bit of sense to me. Can't tell if it really helped or did anything though with potentiating it after stopping the Venlafaxine. (75mg doses)
There's no feeling to re-dose, or any kind of addiction that I can tell so far, either chemically or mentally, I can take it or leave it. There's no crash after it ends, and it feels very clean (until you overdose and vomit).
I'm just wondering why the first couple of times I took it, at 300 and 500mg doses, I didn't get nauseas or vomiting, but now going over 100mg I do. Anyone able to explain?
I won't dare go over 100mg now because the nausea and vomiting just make you feel awful. I kept wishing I had some weed on hand to kill the nausea.
Anyway. Just throwing my experience in here.
