Are muscle twitches a common withdrawal symptom of Lexapro?

When initially prescribing lexapro to me about 2 years ago, my doctor stated that the side effects were much less noticeable with this drug compared to the celexa I had been on, and especially for men. As a now 36 year old male who's been on the drug I can say this, my depression was abated, but I felt extremely "flat" or numb and couldn't experience emotions. Also, my sex drive became almost non-existent and though it was told to me that it is extremely rare for men to experience, I gained 15 pounds which I have tried very hard to get rid of through rigorous exercise and healthier diet. I have been unsuccessful in doing so - and this includes 6 months training for and completing a marathon. After 2 years of counseling, I now decided that I no longer need the depression relief and have started for the second time to withdraw from the drug. I can tell you that the withdrawal side effects are very real. I did a taper down program this time over a period of a month where I tapered from 20 mg down to 5 and now am at 0. I have been extremely irritable and have dizzy spells almost every 10 minutes. My tongue tingles a lot and I have been having extremely vivid nightmares and dreams. My hands don't shake, but my body definitely twitches and I do get the "brain freezes". It is a very weird feeling, but I will gladly go through this to the end so I never have to have another SSDI inhibitor in my body again. I am interested to see if the weight comes off, sex drive comes back and emotional flatness goes away.
