My side effects were:
Exhaustion
Needing to take naps during the day
Feeling unwell, like the malaise feeling you have when you're getting a virus
Getting too hot if I did anything physical, even basic housework
Withdrawal symptoms:
Dizziness unlike anything I've ever felt. Felt like my brain was a sponge and someone poured alcohol into it.
"Swish" feeling in head
Pain in one eye, fluttering in the other
Waking up in the night to seeing a kaleidoscope pattern before my eyes - intricate patterns of swirling geometric shapes. Once or twice a second, it would change (from, say, all squares to all diamonds, to all circles, etc.)
Pain all over my body
Periodically a tingling feeling in one area of my body, or one side of my head
Shakiness
Sleeping even more during the day than the side effects had made me do
Grogginess
Difficulty concentrating/thinking
Hot flashes
Feeling hot and nauseous in brain, if that makes any sense. That's the best way I can describe it. The hot, nauseous feeling branches down my body.
Inability to do anything that requires physical stamina, even taking a walk around the block. Feel shaky, hot, sick, and sometimes nauseous afterwards.
Getting tears in my eyes easily...several times a day
Irritability, impatience
(By the way, this is on a slow taper, with doctor supervision.)
