Parnate 40 mg
I came to him on Effexor, Lamictal, klonopin .5mg,
Prazosin for night terrors
Propranolol for palpitations and panic PRN
Ritalin or Vyvanse PRN
When I would mention taking one of these (which I had been taking for 5 years) he would flip out on me like I was sneaking pills off-treatment, even though they were on my med list and we never discussed not taking them. I knew this week something was up when he denied refills of prazosin and propranolol, which I take baby doses off and have proven miraculous helping my sleep.
He might have worried you began "drug-seeking behavior" by starting to see other psychiatrists and not keeping him in the loop. You should have first sat down with him and told him that you don't think he's doing his job efficiently.
Going on from there, told him what you needed and listened to what he had to say. If you didn't agree, that is the time when you mention casually "I might begin to look in to seeing other psychiatrists" etc. Don't be surprised he/she did this. They all talk amongst eachother.
Sure, they were wrong to "stop seeing you abruptly" aka firing, and instead could have handled the situation better: for example, called you in one last time with refills for weening off all your medication and told you that they cannot treat you any longer.
Every one could have done a better job, could be doing a better hob, and may do a better job if they only took a breath and thought. But this is not the world any longer, especially today.
Good luck G. I may second the notion that you should ween yourself off some of those medications for your safety and future.
