HI ....when I cam off the stuff I had mind/bending headaches for days the only thing that helped was getting out of all light and a cool rag for my eyes and forhead try that......they do go away but its been a few yrs now but if I remember right mine hit about the same time yours did and were on and off for around 2 weeks usuallly around 3 in the afternoon it would hit me check your B/P at the pharmacy it tends to spike coming off this stuff good luck and God blass.......Gnarly
It took my husband about 20 days to get through the full withdrawl of the methadone, depending on your dose it can take up to thirty, but hang in I didnt and I ended up waking up in ICU after dying in bathroom where my husband found me..... Then they really wont give you anything that will help...
Try ibeprofen. That's what helped me.
