They hit me hard. Im close to 3 weeks off and still feel like absolute shit. Sucks.I know this one's a bit old now but kidneys starting to struggle has this effect. It can turn a ten hour half life into 100hours easily. U don't have to be pering blood for this to be apparent .some ppl actually pee a lot more clear fluids to compensate.id be interested to hear it the wds came after five days plus .
