Since after i went back for schooling,i did not do any exercise from March 2009 till now,i am taking baclofen 1day 3times.Sometimes,when i lay down on my bed from my head to my pillow,i feel a bit of giddy and also i feel like my blood is going up to my brain and also feeling like going to faint,and i quickly wake up and back to my sitting position,then the problem immediately gone.Can Sir tell me why this problem happen?The sound when i lay down on my bed is very irritating for me to sleep,something like drilling sound,this sound can only be heard if my house went silent.I think the bumpy problem is probally causes of my sensitive relflexes.I am having massive sweating if i feel hot.
