Magnesium situation....

Curious if anyone can relate:

When I supplement magnesium at night I always feel more relaxed, but I almost always sleep worse. It almost gives me this steady (not strong or anything) focus. I end up falling asleep but it never in a way where I'm nodding off/yawning tired.

When I supplement magnesium in the morning, I also feel much more relaxed but it feels like my brain is operating at 80% - relaxed, a little out of it but not enough to fall asleep/ nap.

I've tried this ~20-25 times with glycinate and citrate. Albeit, never more for 2-3 days. I usually give up after a couple days.

Should I just power through and try for a longer time? using wrong form? can anyone relate?
