would like to explain to you guys a situation of mine and maybe you can help me find the answer. So I was on this sleep aid which contained Diphenhydramine HCL 25mg for 2 and half months. (from this past February 2011-April 2011). I have been off the medicine for 4 and a half months now and I am still experiencing strange side effects. I have had sensitivity to heat, flushed face, fealt sweaty at times,dry mouth, and sensitivity to spicy foods. I have done a lot of blood tests and all my tests have come back with normal results. Everyone of my speacialists have told me that it is just a mater of time before the side effects will go away. So my quesiton is how long do you guys think these side effects will stay in my body for? Will it stay in my body for years to come? or will they go away in a few short months? I appreciate your help.
