Cindy, I am new to a POTS diagnosis, but in a way have a similar job and have found ways to deal with this before I knew what I had. I am a consulting SLP and do presentations for my about 60% of my job in the fall and spring. However, I am not doing this everyday. This week will be hard as I have a 1/2 day presentation Tuesday and all day Wed and Thurs. I find that not standing still is helpful. Thankfully my trainings on hands on with technology and I am walking around a fair amount. I do find in the afternoon I end up sitting off and on. I am recently diagnosed and had always chalked it up to being lazy. Good to know I'm not lazy. I think being able to sit is going to be important to keep your energy up. I thought the tall stool idea was great. I presented all day Friday and the set up was different. The computer was on a podium and not a table so I couldn't sit as there wasn't a tall chair. The afternoon was harder. I have always had such admiration for teachers. I worked in the schools and would work with the kids for 30 min to an hour, take them back. Teachers are the ones that keep them learning all day long. My neuro has recommended granny stockings (I know compression stockings, but I am in my mid 30s and by calling them granny stockings I keep laughing!), they are only knee high but I have not found them to make a difference. Lots and lots of water seems to be a key for me while I am presenting. And here I thought it was just to keep my voice from getting dry. I find when I don't take the time to fill my water bottle it is much harder to get through the days. However, again I am lucky. I am running the presentation and just give the folks a break when I need to use the facilities. I know that is much harder as a teacher. Getting too hungry is also a problem for me. When I am presenting I make sure I have a good breakfast with protein to keep me full. Standing while hungry, even a little hungry, makes me more likely to get dizzy. I find I need to have snacks. Good luck. Amy
