Meditation

Hi guys, I am wondering how many of you all have a daily or quasi-daily practice of meditation in your lives. I used to somewhat frequently meditate before I had POTS. Now I find it’s very hard to relax when I feel my blood pressure/pulse in my head or getting palpitations when taking deep inhalations. Has anyone else had some sort of similar story but things changed? Any tips in general? I can’t meditate sitting upright anymore as I find it too stimulative.
