Husband weaning off anti depressants- it’s awful

Does it get better? His psychiatrist opted to wean him from every day down to every other day this month with the goal to be completely off of them next month. I’ve noticed an INSTANT change and it’s been about a week. It reminds me of how it was before, with the quick temper, getting bothered by things that don’t matter, saying hurtful things, decreased sex drive, etc. All those symptoms were gone when he was on the meds and our marriage was thriving but now they’re back. Is it just his body adjusting to the lower dose and will his mood go back up with some time?

I don’t have any experience with this kinda thing. I obviously don’t want him to have to rely on the meds if he doesn’t need them and I was happy they felt he was ready to start weaning but ever since he started, being at home has sucked. I’m pregnant and due in 2 months. A Little worried, any experiences?

Edit based on comments: I’m not in his therapy sessions, those are private to him so I don’t know exactly what led to the decision to wean but based on what he’s said, it’s that he’s doing so well overall they thought they would try it. He was in a very dark place about a year ago and our lives have changed in more ways than one, all contributing to just overall better mental health. I’ll give it some time and patience, and if he ends up needing back on them in a few weeks at least we tried! Thanks everyone!
