Hey bro, sorry to read about your pain... Alot of good advice here. Lots of liquid. Fruit if you can eat. Even a little walk....
Just remember that the symptoms are NORMAL for someone who was on a 5 day binge.. Probably that may comfort you somehow... Dont play with withdrawals tho. If it starts getting scary you should go to a medical facility... Withdrawals can be lethal... Good luck!!!
