As a former Lexapro user, let me say this:
I first started off with 5mg for the first week, then 10; the 5 was just a safety thing for my mind to get used to it. For the first week and a half, my emotions were exaggerated, i.e. when I was in a good mood, I'd feel elated and I'd be be a bit giggly, but when I was depressed, I was in the pits. I also had to re-learn how to cross the road as I became somewhat over-confident with myself.
After about a few months, my mental health was retreating so my doc, with the recommendation of my psych, upped my dosage to 20mg. Same/similar things would happen, feel great, then feel like shyte, not so much, more like 'blips', but on the whole, okay.
After many more months, my prescription was upped to 30. I was on Lexapro for at least a year and at 30mg, the medicine is worse than the illness. I'm not trying to sound 'offbeat' here, but my plumbing system became very....reluctant to respond and it would be PAINFUL.
After many more months of that kind of mysery and feeling intense frustration of wondering if my life was worth living, I just STOPPED taking the meds. I had enough of taking that shyte and that was it. It was mindfuk.
Even to this day, I'm being told that my personality is different from before...I can't see how, I still have CD, anxiety and my life is still shyte. I used to ask myself which was better, committing suicide, or never being born in the first place?
I do not profess to be an expert in the field of psychology, I'm just imparting personal experience; in fact, I won't be surprised if no-one responds to this post.
