, You were taking 70mgs of Lexapro???!!! I thought the max dose for Lexapro was 20mg. I've heard of people using up to 60 to 80mgs of Celexa, but never Lexapro.
And as far as comparing Lexapro withdrawl with Effexor, Lexapro works pretty much the same as Effexor, hence the same withdrawls. They are both potent SSRIs, with Effexor having some norepinephrine uptake inhibition. But it's the serotonin action of both drugs that causes the bad withdrawl problems.
I wish you both well in your quest to get off these meds, I know it's not easy.
