I have been given Gabapentin and Baclofen to be taken three times a day along with Co-codamol. GP gave these for pain and spasm in my left leg which is new for me. My right leg has rigidity but is fairly numb and weak but pain free with a drop foot on the right side I started taking these tablets last Thursday and since then I have felt very drowsy and can hardly keep my eyes open. Also feeling quite "spaced out". The spasm in my left leg is somewhat improved and certainly not as painful. Do the side effects of tiredness etc improve over time? The improvement in spasm and pain is good but I don't think I can continue with the tablets if the drowsiness and tiredness do not decrease. Can anyone who is taking this medication please advise.
