how long have you been using and what is your habit like?
i was able to use daily for a surprisingly long time (like over a year) without getting withdrawals so you may be OK.
if you do get withdrawals you will probably start feeling it very soon, ime it will get increasingly worse until day 3. the worst day. the day i would always fuck off that attempt to kick despite knowing that if i could just make it to day 4, things would start getting better day by day.
do you have any comfort meds to help you through? something to help you sleep will be very handy. i'm sure someone on here can tell you the name of the thing that supposedly helps with the restless legs, never tried it and don't recall but for me that was one of the worst bits of withdrawal so anything to help with that would be a good shout.
