Have some godamn patience, son, puuuuhhhhllllleeeessseeeee........
I've been through it many times (you may also want to note i've been through pod withdrawal amongst other things) and it can be pretty fucking bad depending on what you withdraw from (ie, UEI or 250x extract or something lower-end like RVI). I get really restless legs, BAD depression and anxiety. I feel cold no matter how much clothes I wear and my eyes water uncontrollably, accompanied with CONSTANT yawning, seriously like every 30 seconds all day.
Just yer typical opiate-style withhdrawals. You are only averaging about 60g a week which is less than 10g a day. I wouldn't worry too much. I had a habit of around 60g a day at times, going through at least a half kilo a month, at least and it wasn't the worst thing i've ever experienced.
Some people aren't that susceptible to kratom withdrawals. Grab some loperamide if you need, have small doses of codeine to ease yourself if you need to.
But dont worry about it is my main peice of advice. It's coming either way.....I highly doubt it will be that bad.
