Hello,
Sorry you are feeling this way, it is truly horrible.
I don't know what advice I can give that will be helpful, but I came off Flu after about 2 weeks because I couldn't cope with the side effects. I think I got the majority listed. Vomiting, upset stomach, not sleeping, eating, anxiety attacks, sweats and shakes, horrible leg and neck pain. The works. I was having so much time off work, I am suprised I kept my job! I never had the depression, but just a strange sense of detachment, like I wasn't me anymore. I was emotionally numb and had very slow reactions, I did not dare to drive on them. I also found I was drained, just exhausted but couldn't sleep.
My doctor advised to give it time to settle and level out, but I needed to work (money is the root of all evil sadly) and on the tablets, I found it harder to get through a day in work than it was tackling anxiety in the first place. My performance was minimal, the hardest part of the day was getting to work, then it was a battle to not throw up or have a panic attack and act normal.
Although I was assured at week 4-5 the majority of symptoms would ease, I just couldn't take it.
I stopped cold and 3 weeks of withdrawal effects later I started feeling marginally better. About a month on, I felt like myself again, appetite back, weight slowing re-gained. I joined the gym and was getting happier, and had two amazing weeks. My anxiety seems trivial compared to the chemically induced attacks I was having.
However now 2 months on and my anxiety / panic attacks have come flooding back in full force, I can constantly upset and drained because of it. It's exhausting, I am barely sleeping and it's getting harder and harder to get through a day in work and I think my employer is losing patience with me as it's not "physically" showing like a broken arm or something. It's like I have reverted to how I was before I considered the tablets!.
I am now wondering had I just stuck out a little longer would I have been rid of this horrible feeling and lost the initial side effects. I am back to square one now trying Sertraline which is so far sounds just as bad and dreading it as I know what will happen for the first month or so.
Sorry if this doesn't help. Just weight up the pro's and con's to stopping or not. For me I benefitted short term by stopping but longer term, I am probably looking at more time off work while I adjust to the new meds (if I even try them).
Annoyingly there is no quick fix!
