Suggest Treatment For Headache

I am a 27 yr old female. I have had headaches for years. Lately I have noticed it to be around my menstural cycle, and also as the weather changes. I have been constantly feeling dizzy, sick and tired. I have not been overly stressed but it is getting very depressing feeling this way all the time. I have been diagnosed with TMJ but do not have 1800.00 for a mouth piece. Any advise would be helpful.
