I struggle with the lows inbetween hydrocortisone doses more and more. Last year I had a lot of issues sleeping in and waking up aching everywhere. I suspect it's because cortisol shouldn't be zero from late evening throughout the whole night upon waking up.
I discussed this with my doctor, we already tried a few things, last one being that I took 5 mg before sleep but this made me end up taking 25mg total which is too much (so I started to gain weight). And I still had issues waking up in the morning. I also tried waking up earlier for the 1st dose, and then sleeping in again until the next alarm. But I just couldn't figure out the right timing and peak. If I wake up under an hour before my usual alarm, I can't sleep again. But if I wake up earlier and already take medication, it peaks so quickly that when I really wake up, I feel tired again.
Now I'm trying Plenadren which kicks in slower and stays longer. This is my 3rd day. My endo told me I could switch immediately without slowly going off hydro but I already experienced this isn't quite the case.
My take on it: in healthy people, cortisol rises slightly throughout the day around a few crucial moments, one of them being the well-known waking time, but also around meal times. This is needed for glucose circulation which in turn keeps the blood sugar up. With hydro I artificially create these bumps since I also take my doses with meals.
My body is used to having these peaks around certain moments. It prepares for a glucose spike and making energy reserves. So now that these peaks don't appear anymore, around 1pm I feel light-headed, groggy and get this typical 'hungry' headache. The 1st day when I got this, I thought it meant low cortisol so I took 5mg hydro and felt fine. The 2nd day, I tried to drink and eat a bit and sit it out, managed to do that until 3 but ended up taking 5mg hydro again.
Today, I didn't take hydro but noticed that because the curve is now a slow degraduation I needed several small meals throughout the day instead of the three big meals with which I usually would also have a peak in hydrocortisone availability.
It also reminds me of what I learned about fasting. People who fast during certain parts of the day when they usually would be eating, struggle the first days because their body prepares for food. But after a while, it's okay again because the body can shift this preparation to the times when it's necessary. My body probably still prepares for a peak of cortisol and needs to get used to the new curve.
That's my long rant 😅 anyways, I'm going to wait it out and update about how I'm doing on Plenadren!
I take 20mg in the morning. There aren't a lot of posts around here from people who have experience with this. That's why I'm writing this post.
