I don t feel well, haven t ever since I quit smoking about five months ago. I am always tired, don t sleep well, try to eat healthy but continue to put on weight. I try to walk or bike in the evenings after work unless I am too exhausted. My doctor wanted to do a sleep study but my health insurance wont pay for it and I cant afford the cost of the study. I have a history of hypothyroidism, but my doctor doesn t think its thyroid related. Im having headaches the last few days like a belt is around my head getting tighter. Any suggestions.
