I would raise the dose, found it worked good for me 100mg+... I sometimes had to use betablockers tough to lower the BP, (For me i get a raise of BP from Parnate)...
About your other question about tests, Dr. Stahl writes this: (from neiglobal.com)
How come you think raising the dose would help with the GAD and OCD? What mechanisms in a higher dose do you think help with GAD and OCD?
I feel like a larger dose probably would work better for me, it's just I get bad insomnia at 50-60mg, which makes it counterproductive and ineffective. If I could treat the insomnia, then I could actually give the Parnate more of a chance to work at a higher dose.
