yesss!!! take the pregabalin!! i bet (only assuming) it will make your WD almost nonexistent . lyrica and remeron are definitely OK to take together. however, you will definitely have marked increased sedation, but nothing deadly. while they both produce somewhat heavy sedation, both lyrica and mirtazapine only slightly depress the CNS. in other words even though you will feel like you could fall asleep standing up, the combo is highly unlikely to cause you stop breathing. remeron's sedation comes from poweful H1 antagonism, and anti-histamines cause very very limited CNS depression. lyrica is a complex drug, not showing any affinity to NT receptors such a dopamine or serotonin, and only causes limited CNS depression.
i am talking out of my ass here, but IMO/IME codeine/ hydrocodone causes more CNS depression than either of the two. .you are perfectly safe to take them together, just dont drive!!!
your good, but i would only take the mirtazapine at night as it will definitey cause you to fall asleep. i.d take the lyrica throughtout the day fior anxiety, and remeron at niight to sleep. the thing about lyrica is that it lasts alll day for me . if i take some at 11am, i will still feel the effects at 10pm.
if i were you i would take 100-150mgs of lyrica - 3 times per day. and 15-30mg mirtazapine at night for sleep.
