Serc is not FDA approved in the US. It has never been shown to have a worthwhile benefit.
Have you had a vestibular evaluation yet? Has anybody tried the Epley Maneuver or similar therapy for your dizziness?
You can see a do it yourself video of the Epley Maneuver on YouTube. It is not a risky treatment.

59 years old, retired due to disability, married 34 years, father of three, grandfather of four, Suffered a serious concussion at 10 years old (1965) stopped most driving after concussion at 46 years old (2001), Post Concussion Syndrome/Multiple Concussion/Impact Syndrome with PTSD, immediate/short term visual and auditory memory problems, slowed processing speed, visual/auditory processing difficulties, insomnia, absence seizures, OCD, 14 concussions since first concussion at 8 years old, Taking paroxetine for 14 years and gabapentin for 12 years. Added L-Tryptophan and stopped paroxetine after 3 months of tapering. I currently take 100 mgs of 5-HTP AM, 500 mgs of L-Tryptophan at noon.
As of Nov 15th, Due to high stress issues resulting in PTSD, docs put me on 3 meds. Clonazepam but only for 30 days ) .125 mgs twice daily (Doc presc. .25 mgs 2x daily but half a tablet is good) , citalopram (Celexa), an SSRI , and olanzapine (Zyprexa), an atypical anti-psychotic that usually causes weight gain before bed. I lost over 30 pounds since mid July. It just stopped the weight loss. Took me off the gabapentin. I am feeling better than I have in years.
This great feeling only lasted a month. Back to the same old PCS doldrums.
May 2014, I am off the olanzapine due to a 6 fold price increase. Back on 600 mgs of gabapentin before bed.
I am also taking L-Theanine to help with GABA regulation
