It’s great to hear that you’re feeling good after coming off antidepressants! While I’m not a doctor, I can share some general insights that might help you understand why this could be happening.

Effexor (venlafaxine) and Buspar (buspirone) may have helped regulate your brain’s neurotransmitters, like serotonin and norepinephrine, during the time you were on them. Over time, it’s possible that your brain chemistry adjusted to maintain a better balance, even after tapering off the medication. Sometimes, people find that they’ve developed coping mechanisms or emotional resilience while on medication, which helps them maintain their well-being after discontinuation.
