Methadone Hydrochloride and second time

daily headaches, waking every hour till 2 am, vision, but mostly the headaches are what are bothering me the most. This is my second time on methadone. the 1st time was 8 months start to finish with 3 years clean then a relapse. I realized that both times I had headaches. Why the headaches? I feel like I am losing it. I'm trying to be a wife, mother to 3, independent rep and so on. Am i alone?

I have been on Methadone for approx. six months for a second time and i have been getting extremely clammy and i sweat and have heat attacks so severe, i'm so afraid of this summer, afraid i might have a heat stroke. It seems my body cannot control my heating system. Someone suggested i might be starting menopause, but i do not have sweating spells unless i'm moving around or even standing ,or if it's hot, not like hot flashes in the middle of the night for no apparent reason. Also i have always had the best blood pressure, now i have high blood pressure since using methasone for pain control and i have to take Toprol. Doctors think it's just a coincidence but i know it's the meth and i am slowly weaning off. I just hope my body can return to normal. Has anyone had these same problems.
