I think you are saying the fumes from the 36.2% HCL were too much for you. I know what you mean and I do the HCL diluting outside and make sure the wind is blowing the fumes away from me. The fumes are very strong.
Once you have 1 liter of 4% HCL, you would then make One Bottle CDH by doing the following:
1. Put 220ml of water* in a glass bottle** of about 300ml size
2. Add 10ml of unactivated MMS to the bottle (22.4% sodium chlorite)
3. Add 10ml of 4% HCL to the bottle and immediately cap and shake the bottle of solution to mix well.
4. Put the bottle of solution in a dark, room temperature place for 12+ hours
5. You should now have a bottle of CDH with a nice yellow color
6. Store the CDH in a fridge if possible
7. Start hourly dosing at maybe 1ml per hour and work your way up
Let us know how it goes.
*(distilled water is best)
**(Schweppes bottles work very well and their cap seals well)
