Hello doctor, I took an overdose of my late mother's Morphine sulphate tablets which resulted in hypoxic brain damage and this resulted in me having these uncontrollable tremmers in both my hands and jaw. Now I have been prescribed Pregabalin 50 mg daily but have just recently been giving a few Valium which stopped my twitches in my hands and jaw and I think these would be beneficial to me but I do not know what to say to the neurologist. I do not want him thinking that I am going to abuse them which I will not. But I do not know how to go about trying to explain that they really are helping me.
Hi.  In view of the symptoms you have been suffering with, your diagnosis fits into a case of essential tremor which is the most common movement disorder associated with trembling, there is sometimes shaking of fingers, hands, and head. Particularly, increased with action as during writing, eating, dressing and so on. According to guidelines, Pregabalin and other drugs like Propranolol, Topiramate, Levatiracetam should be tried and they are known to do miracles. Pregabalin started at a dose of 50 mg is increased gradually to 75 and so on upto 600 mg according to the response. Now coming to Valium, yes as you said it is a very good drug but long term use causes increased muscle weakness, fatigue, memory problems, dizziness, ataxia, loss of libido, restlessness, drowsiness and so on. I would advise you to communicate with your physician and try other good medications which also will act similar to Valium.
