Him Mich,
i can really feel for you. this is a tough time, i know it is very difficult, but very normal for having jumped off where you did. all of it. it does not sound as though anything you are experiencing at this point is out of the normal range of symptoms for your stage.
i agree with you - how can anyone be employed and/or take care of children or a parent in withdrawal? i deliberately waited to quit the C until after i quit the job i had. i knew it would be rough, but not this much.
i didn't really notice a difference in food taste but i wasn't eating much either due to nausea at that point. i don't doubt the light sensitivity, but that has been an issue for me since i was much younger, so while i noticed it, it was nothing new. the motor sound is likely tinnitus. again, that is something i've had for at least 10 years prior to taking any anti-depressant. the result of loud music - i worked in the music/entertainment/radio industry but in the 80's/90's no one thought about ear protection. i know others here said they developed tinnitus as a side effect while on the C, others as a withdrawal side effect. i don't know if it lasts in those cases. mine is pretty much out of control but i've learned to live with it. mine gets worse over time, but again, that's due to actual self-imposed damage. you haven't mentioned pain as a symptom. that was a biggie for me in addition to anxiety. it lasted about 6 months. at times it was terrible, my joints and muscles. i never had fibro, but during that early time period it felt like what i've seen described by others. i have had arthritis since prior to being on any anti-d. cymbalta is used as a pain med, and i wondered if it masked some of my arthritic pain. however other than my knees and fingers, the pain is gone. my knees and fingers have bothered me since i was in my 30,'s - i turn 56 on tuesday.
my theory is that whatever conditions that cymbalta is effective at treating, actually manifest when coming off the drug. it makes sense that the symptoms for which we took it would re-emerge, but developing the others seems bizarre to me - but its somewhat consistent for us all. those who took it for pain, not mental health, often develop depression and anxiety in withdrawal. and those who took it for depression (me) and/or anxiety develop pain while in withdrawal. however, the pain seems to fade for those of us who took the C for mental health issues.
i suspect that the majority of your physical symptoms will subside in another month or so - maybe less since its already been 3 weeks for you. for me, nausea was gone within about a month. other gastro/intestinal issues about 3-4 months but were tolerable, just kind of a hassle needing "to go"more than normal. still comes and goes with anxiety levels, but that's true of anyone with anxiety for any reason. i lost the 25 pounds i gained on the C in 3 months. i am 5'4" and went from 140 to 115, which is what i weighed when i first started taking anti-d's. chills/the sweats were gone by about 3-4 months for me. muscle twitching of the eyelid is a common stress/anxiety reaction in anyone. also numbness in the face. numbness comes and goes for me depending on anxiety. other muscle twitching has been common with me since childhood. eye, arm/leg muscles. never major. aching teeth also, due to grinding. brain fog/focus/concentration/irritability are all directly related to anxiety for me, so they come and go. its been bad recently, the holidays and loss of a pet cat have exacerbated it. overall my anxiety is much much better.
for me, the anxiety reduction is a direct result of actively working on it. anxiety does not go away "on its own". while the trauma of withdrawal causes it, its very easy to develop the classic "fear of fear" - that it won't go away. i believe it is a form of PTSD. it continues due to reactionary/habitual thoughts reacting to the initial trauma that no longer exists. in the case of cold turkey withdrawal, the body suffers a dramatic and immediate reduction in serotonin and norepinephrine levels that initiate the anxiety but as our normal levels return, the fear of that initial fear, conscious or not - is what triggers the fight or flight response of the sympathetic nervous system in anyone. for me, CBT and info i've learned on various web sites have provided me with the "solutions" to my problem. the good news is that we will be okay. i do not believe there is any permanent brain damage due to cymbalta. i was on one anti-d or another for 18 years, from the age of 36-54. if i can get through this anyone can. but i admit after 18 months its still a work in progress.
