Withdrawal in waves??

Quit cold turkey

first 4 days was brutal, depression, exhaustion. no motivation

the next few days i didnt feel too bad. lifts at the gym went up, felt a lot better than expected.

today though, woke up feeling like shit. exhaustion, lack of motivation. mild depression. headache. no idea why i regressed. pretty much just stayed in bed all day so far.

Anybody else get withdrawal symptoms in waves?? bad days followed by good days then back to bad?
