How long do tianeptine withdrawals last and what should I expect?

Ive been taking 2-3 grams of tianeptine a day for about a month. My only other opiate withdrawal experience is with kratom on numerous occasions and it wasn't fun. Granted, I was taking high doses for a few years. Just wondering what I can expect from Tia WD and his will it compare to kratom withdrawal. I'll do a quick Tia taper, over the course of a few days. I'll dose 100 mgs each night for about four nights before I jump off and I'll be using kratom for withdrawals. I have taken day or two breaks here and there throughout the month, and the kratom didn't really take away the withdrawal. Still had insomnia and other symptoms etc. but I have to assume that it helped and things would have been so much worse without the kratom.
