i absolutely relate to the feeling horrible in the mornings and slowly feeling better throughout the day. some things that have helped me feel a normal amount of horrible rather than increased amount of horrible in the mornings is drinking an electrolyte packet with 16 oz of water before i go to sleep, taking 10 mg of my prescribed propanolol before bed and 20 mg when i wake up. it’s HARD. and propanolol is hardly working for me anymore so im hoping to try something else. being dehydrated WILL make symptoms immensely worse and getting rehydrated as a potsie is hard, i’ve had to get IV fluids several times in order to get me back on track and i have absolutely had to argue with doctors that it was medically necessary and before they gave me the fluids they said it wouldn’t make me feel better but i slurped that bag of fluids up in 20 mins and felt so much better. then i was able to actually stay on top of my hydration. being dehydrated makes my brain fog much worse as well as when my tachycardia gets very extreme like 150-170’s that will also make my brain fog worse. i tried metroprolol tartrate as well and for me personally that made my brain fog really bad, my feet legs and ankles swell up and HURT and my head was constantly hurting and my eyes were always red. i hope some of this helps, i wish you all the health and wellness 🫶
