Seasonal sickness

well this is kind of a rant, but hoping i might get some advice as well.

everytime the weather changes, like summer to fall, and winter to spring. i get really sick. headache, runy nose, sore joints, cough, hacking up phlegm, etc. im sure im not alone on this??

over the last couple weeks, ive cranked up my workouts in the gym, and been eating good. ive put on about 5lbs, which i was really happy about considering im off cycle at the moment. i was just about to start a 6month cycle of HGH on monday, as well as doing an 8 week cycle of anavar with it. and i just came down with this flu/sickness shit again. one day and ive already lost 3lbs. its really hard to make permanent gains, when i get this shit twice a year.

anyone else get this?? and have any advice about it??
