Quit lexapro 20-10-0mg in seven days

Quit lexapro in seven days, 20 to 10 for 3, 20 cut in 3 for 4 days to zero and feel way better. My joints were so sore for the last 3 months on lexapro, I was incredibly dumb, could not stay awake and was gaining weight fast. I have felt better every day since I dropped for 20 and feeling so much more energy. Only side effect I've experienced is occasional very minor headache. And no I didn't bother asking my doctor, I couldn't handle being lethargic, dumb and gaining weight. See what happens from here but can anyone relate a similar experience? Maybe I never needed to start with?
