Don't screw yourself over 5lbs.
If weigh-ins are Friday morning, drive up on Thursday.
For 5#, eat normally until meet week.
On Tuesday eat high-salt and bump your water up a lot, like 1.5-2 gallons min.
Wed Cut salt out completely and keep water high.
Thursday just drink distilled water as needed and stop eating around noon. If you are still over by the afternoon just stop drinking.
If you are over Fri. morning by a pound or two ( which I doubt you would be) just hit a sauna.
This can easily pull 10# off of my 315 waling-around weight and because it's a short cut it all comes back on easy. Don't deplete slowly, don't use any water pills, this cut is easy.
After weigh-in on Friday start pounding pedialyte and carbs as hard as you can without getting sick.
For my last meet I cut like this from 315-302 ( over shot 308 because I know a strong buddy was moving up from 275 and I wanted the best chance to win)
After weigh-ins I started eating. That day I took down a box of pop tarts, two family packs of oreos, 2 ihop breakfasts, Famous Dave's for lunch, two coconut waters, 3 pedialytes, a large pizza and some italian nachos for dinner, and some fruit before bed.... we both went 6/9 and missed 3rd attempts on all three lifts that would have put us over 2500...... ended up totaling the same and he won by being 10 lbs lighter. I lift geared and had to not bloat too much so I still fit in my gear. If you are going raw you can go much higher sodium and pound some chinese food too.
Good luck.
