Hey, that's amazing that you cold shower every day. You probably don't need the tub! I don't have a bath but bought a special tub thing for the garden. I've been Hoffing for a few years and when I do it regularly it makes a huge difference to my anxiety and general state of mind (always regret it when I get out of the habit). I bought the tub as I wanted to find a coping strategy for bad days that didn't come in a glass...
I think it took a few weeks for me to get the hang of the breathing especially as I was doing it without guidance at first. A lot of people are seeking the lightheadedness as it's like a high but it is emphasised that you go at your own pace - after all you are basically hyperventilating. And of course never do it IN water or just before, especially alone.
The first time I went in, I made noises probably made the neighbours wonder wtf was happening

Good luck to you if you decide to give the breathing another go x
