My pdoc started me on trileptal a month or so ago, he also had me start wellbutrin and took me off my effexor all at the same time, I got horribly sick, I finally got him on the phone, and he old me to go back on my effexor and stop the wellbutrin and to just try a half a tablet of trileptal, just after 2 days I was horribly sick again so i just stopped them. I wasn't a high dose that you are, but he did make it clear to me that I had to start with a small dose and work my way up every 5 days. He also admitted t me that he would never take any of these meds. Makes me wonder why he is asking me too. Now I am just on my effexor, I realised I had to stand up for myself, there are meds out there that don't cause such side effects. If you feel you are not getting better, then talk to your doctor and tell him how you feel, I think it should be up to the patient to take some of these meds, but please never just stop a meds without talking to your doctor, the side effects from doing that can be even worse. Like I said I couldn't take them and I have acid reflux, and taking all these meds and the changes has triggered my acid reflux to act up and had to get my stomach meds increased, I feel tons better now. Talk to your pdoc, let him/her know how you are feeling, ask her/him if they would keep taking them if they made them so sick.
I really feel for you, and my heart goes out to you, I hope that things get better for you soon.
I have a bulging disc, pinched nerve, ddd, bipolar/depression, anxiety and acid reflux.
The meds I take are oxycontin, oxycodone, effexor, clonazepam, pariet.
