Hi, I have Cerebral Palsy spastic type ,  taking muscle relaxant & physio sessions regularly For the last few months I have been facing sleep disturbance and back pain mainly SI & hip joint area and it keeps shifting from one joint to other with every moment Earlier I had tried Pregablin NT 50 & defcort 6mg chemsfort and recently my Neurologist gave me Gabapin 200 nt along with Cal grow forte but I am feeling extreme drowsiness next whole  day . My B12 is Nrml and Vit d is 30. Pls suggest what  can I do should take only Gabapin or switch to Pregablin for sciatica pain . Thanks in advance
