I was on 10mg of Lexapro for over a year then on 15mg for about the same. I think it was about 3 years all together. I barely tapered off but didn't realize the complications of withdraw / discontinuation syndrome at the time. After about 3 months I can't shake the symptoms and it's debilitating. I'm still having brain shivers / clicks / pulsing (though not as severe) which move from my brain around my nose, inside of my mouth, sometimes down the back of my throat, around my temples.. Sometimes my head shakes a tiny bit when I turn my head, but it's not too frequent and seems fairly minor. I think I need to go back on but now I'm reading I may have missed a reinstatement window?

Please Help :(

Will it work if I go back on and about how much should I take?
