How do you know what you're feeling is withdrawal? You're on a lot of very heavy meds and what you're probably feeling is a lot of side effects. You could be feeling some problems with overdosing on affecting your neurotransmitters, such as serotonin syndrome. The problem is, you don't describe for us what it is you're feeling -- the symptoms. Withdrawal symptoms can happen when you're taking your meds, because most of these drugs don't stay in the system all that long. For some people, they start to get withdrawal before their next dose. But when you're on 4 drugs, it's almost impossible to tell what's causing what. Tell us exactly what you're feeling, maybe people who have been on the drugs you're taking will recognize something specific.
I suggest you look up lamotogene and Vivance. Both of these drugs are very powerful and you cannot miss a dose or increase the amount without first talking to your doctor. I do not know if this has happened to you while taking these two...they are serious seizures meds, very potent.
Even when taken as prescribed your body can become accustomed to that amount and develop tolerance, making it possible you need to up your dose....Please talk to your doctor, Although for him to say "hm that's weird" says to me he does not understand the drugs he has given you. I had this happen to me. Doctors are easy to prescribe drugs they know nothing about--yes, it happens all the time.
EVEN WHEN TAKEN AS DIRECTED YOU WILL BECOME ADDICTED AFTER A TIME.
Paxilled is right. With you taking that many medications it would be hard to identify which med is causing the symptoms and there are other things that have to be asked in order to even start the investigation. What symptom you did state was a feeling of vertigo. Since you are on all your meds you can rule out withdraw. So the next possible source would be side effects. I did it see anything in your meds or response that would make me believe that to be the issue. Moving on, the next thing I wondered was why you are not really on any meds that would be specific for major anxiety. You are on basically 3 antidepressants and vyvance. Were you ever on an anxiety medicine like xanax, valium, or klonopin? Do you drink?
