Hi and welcome
You have been given great advice already and I can relate to crashing fatigue
Karma well and truly hit me hard as I was (and still am) a believer that energy does create energy BUT crashing fatigue is different ! It got me bad, it's not just tiredness, I feel like I've suddenly been drugged, or like I've been given GA and I'm fighting it, sometimes it's a soothing nap I go into but sometimes it's a scary one, like I'll not wake up! I can't describe it any other way, and when it happens I have to ride with it and my vision goes terrible (double/extra extra blurry)
It's less frequent for me these days but still on a weekly basis, and i think it may be due to introducing supplements, iron , all the Bs, with extra B12, and C&D.
I'm sure I read thyroid fluctuates a lot during this phase of our lives
I have neurological symptoms coming out lately and GP has referred me to see a specialist, I live in hope that something (treatable) suggests why I get this fatigue but I don't hold my breath, as it's such a difficult set of symptoms and so many reasons for them
I hope you get to the bottom of it
Low estrogen is never the reason for me as I've been on maximum dose since my hysterectomy 16 years ago at age 32
