Hello Frouke,
I only take 1 in the am by 8-8:30 am.
I do not take one at night. So I cant say if its withdrawal.
However, to all here, please consider having your estrogen and progesterone levels tested. You may have excess estrogen. That can cause one to cry.

I have had breast cancer. 10 years out in clinical remission. An endoscopy revealed my bc came back in my gut lining. Yes! And i KNOW it was stress.
Its partially SD, sympathetic dominance. And its definitely my gut.

You might try a new diet. Seriously, to see if what youre feeding your gut likes the new foods.

Try green juices. Whole foods makes them. Get the small size first.
Try the Green Goddess and the Apple snap. I take out the lemon and ginger cuz its too much for me. I can add my own. If you have Costco, get the organic carrot juice in the fridge section.. its 3 bottles. May want to try the Dragonfruit juice, too. Its on sale right now.
Eat just salads for 5 days and a bit of Bubbies plain sauerkraut in the deli section. Fermented foods are great for your stomach. Just 2-3 table spoons once or twice a day. You can put it on your salad.
Give this a try for a week or 2 and see if your body is happy.
Also start walking and/or get a rebounder. Jump with tears if you have to 😂
Start reading a Psalm in the am and pm. Let them be the first and last things you do in your day.

Also, get a journal and start at blessing book. Before youre too tired for bed, take 15 minutes and write out the blessings you were given that day; a friendly smile, a kind word, etc… whatever youre thankful for.
Youll be surprised how this calms you down and brings you joy.
This is a fierce battle. I dont even KNOW why the tears come.. and if I have to THINK about it, i know its in my mind first!
Thats when I turn i turn the tears over to God and do what I need to do even if im crying.
Dont let the tears DRIVE YOUR LIFE. You move WITH them. Dont let them capture you useless.

Try your best and document whats going on to see if you have a pattern.
