Thanks for the update Coxy. I'm sorry that you and your son are not feeling better. I appreciate your honest feedback on this whole experience. I just wanted to add that I get problems with not being able to sleep, tired but wired feeling and upset stomach when I've overdone things. It's like if I push past my limits then the accelerator pedal gets stuck in the overdrive postition and it can takes days to calm down. I just get more and more exhausted until I finally crash and can rest again. I sleep better and feel better if I stay within my limits. Of course life demands don't co-operate with my limits so I'm afraid this overdoing things happens rather too often for my liking. I wonder if that might help you and wonder if your symptoms are because you've been overdoing it. Of course we are all different so it might be totally different for you.
