Pregabalin with Mirtazapine- advice please

Hi
I was on gabapentin a few months ago as a trial for migraine (200mg for 3 weeks) but i had nerve pain /paresthesia side effects, depression and increased anxiety and stopped it cold turkey- which was a very very bad idea- had rebound insomnia, anxiety, agitation, muscle pain etc I think Im still suffering the effects 2 months afterwards

Anyhow I was put on Mirtzapine 15mg for the depression/anxiety 15mg at night. Its 4 weeks now and the depression is lifting but anxiety is very bad- mirtazapine seems very stimulating and I think the noradrenalin is increasing the anxiety especially morning still lunchtime.
I still seem to be suffering windows of gabapentin withdrawal- stinging nerves in my back and legs, but maybe this is mirtazapine side effect
My psych suggested I add in some pregabalin for the anxiety , initially 25mg in the morning

Not sure if this is a good idea since I didnt have a good time on gabapentin but maybe adding the pregabalin back in would reduce the withdrawals Im still experiencing?
I know everyone is different with meds but interested in comments

The combination is supposed to work well, also known as California rocket fuel. Am on Pregabalin, but with Venlafaxine not Mirtazapine.
