I’ve been on lexapro for about 8 years now. I tried twice before and even used St. John’s wort as a replacement but it didn’t work. Had bad withdrawal effects. However this time I’m older and better resourced. Seeing a therapist and holistic medicine practitioner, started exercising and taking supplements, juicing, changed my diet (cut gluten and sugar - dairy is a bit hard) and I’ve reduced to 3/4. On day 3 and I still feel ok. I guess I would only know about a week after.
