Hi, Nana, and welcome! I'm sorry we have to meet this way but we do have a wonderful family here.
I saw that Debbie mentioned the Serotonin Syndrome thread. I did put that in Fibro 101 so you can check it out there without having to hunt for it. Fibro 101 is the first thread on the forum and has links to good info about fibro and you will learn a lot.
I take a malic acid/magnesium supplement that has helped me with pain and and fatigue. There is a link about these in Fibro 101, too, and it explains how it works in the body. Malic acid is found in apples but I'd have to eat a bushel to get the amount I need! So, you might want to check that out. It has helped others on this forum. But, with fibro, what works for one doesn't necessarily work for another. These aren't expensive so it would be worth a shot to try them. I get mine at Puritan.com and they are having a sale...buy one, get two free! Can't beat that!
Since you love your job, I wouldn't throw the towel in just yet. I'm glad to see you are getting off some medication because some medications can make you tired. Also, pace yourself when you are at home. Save that energy for work. Try to get up as much as possible and walk around during the day. That helps with pain and helps with energy. I walk at least a mile before breakfast and that helps give me more energy. Also, there are some stretching exercises in Fibro 101 that you can do at your desk and this might help, too. They are done sitting down. Do put yourself on a sleep schedule. This helps in falling asleep. Rest is so important with this illness.
By the way, one of our mods has a wedding cake business. She has fibro, diabetes, and arthritis but she still works...a lot in the "wedding months". I can't imagine leaning over to decorate cakes! She has found ways around her problems and continues to work. Her motto is "Keep on keeping on"!
As far as the fog goes, don't stress over it. That makes it worse. Dig out your sense of humor and your great attitude and you can take on the world!
I hope something that I've mentioned helps you to feel well enough to keep doing what you love to do. A positive attitude works wonders. Let us know what you end up doing. We really do care about you.
I'm so glad you joined our family and I hope to hear more from you soon.
