New to methamphetamine production

[LoonieToonie]

I'm fairly new to producing methamphetamine from Pseudoephedrine and i must admit this forum has helped a lot understand the chemistry behind it, I've been studying it for a few days and this is what I've managed to learn, Feel free to correct me if I'm missing anything!

Chemicals:

Pseudoephedrine (Sinutab medication)
Sodium hydroxide (Caustic soda)
Iodine Solution (Povidone Iodine Sol 500ml)
Sulfuric Acid (Drain Cleaner)
Ether (Methylated spirits or Paint thinners)
Table salts

Is there possibly any ingredients I should look out for that may ruin the synthesis, or cause the chemicals reactions to fail?

Also, I'm using this method I found on this Forum:

The title may say that he is using "Ephedrine", But if you actually watch it, He uses 3 boxes of 44, 30mg Pseudoephedrine tablets, Not sure on the exact brand
Also my tablets I'm using each contain 30mg Pseudoephedrine, 500mg Paracetamol, Will the Paracetamol get in the way?

I want to use the exact same method in the video, Will everything work fine with the chemicals I have listed?

You can separate the Pseudoephedrine from the Paracetamol with anhydrous acetone. Or even better an acid-base extraction with sodium hydroxide and DCM as a solvent.
