Susan A.Valerie, Yes I am the same. I get dizzy, headache, lack of concentration - if it goes too long a stomach ache - when my meds are late. If I sleep in on Saturday (I normally take my dexamethasone at 8am) even till 9:30 or 10:00 I will start to not feel well. I know that it’s a meds issue - an hour after taking my Dex - I am fine.
I’m a teacher and I have scheduled teaching math to my 5th graders at least an hour after I take my Dex. Otherwise my concentration is lousy.
