Antihistamines calmed my extremely distressing luteal depressive episode???
About a week ago, approximately 10 days before i start menstruating if this cycle is regular, i had a pretty bad depressive episode. Didn't eat, slept and cried all day, my mind was a mess filled with existential intrusive thoughts (i have OCD), depressive thoughts, despair and SI. My mom is pretty worried about me and brought me some of her magnesium supplements, hoping they might help (i think there is some scientific backing on this but don't quote me on that). I'm also terribly allergic to dust and pollen, and with the change of the season and wind picking up I've been a mess. After 3 days of pitch black depression, i took magnesium and cetirizine and went to sleep, expecting my misery to last until my first or second day of bleeding. Next morning i woke up fine???? I didn't even realise i was out of that mental state until like midday and i was like, i can function?? My brain doesn't catastrophize, i have a normal amount of intrusive thoughts (i still have ocd ofc but WAY more manageable) and a lot more mental clarity to deal with them. It took me a couple of days to make the connection between me being ok and the magnesium and antihistamine, but since i know that magnesium has to sort of build up in the body, I'm thinking it's the antihistamines.
Also all my physical PMDD sintoms are still here but they have always been the easiest part to deal with for me. Searching online for other ppl's experience brought to this sub but i still don't know anything about this.
What is the general consensus? Is there any science behind this and studies i can read? If there are any I'd like to bring them to the attention of my doctor when I'll ask what he thinks about me taking cetirizine long term for this reason.
