Been taking 150mg for years. If I dont take at the exact same time I get withdrawal... horrible brain zaps and vertigo... so wanted to come off. Weaned as per MD instructions (4 days at 75 mg then start on Lexapro 10mg. Been taking Lexapro only for 4 days now. No brain zaps but dizziness and diarrhea... pretty severe. WHEN WILL THIS END?
