I have been taking 15mg of adderal everyonce and awhile 2-4 times a week and, iv noticed get overheated, very quickly is this common? I sweat a lot more which is very emberrising and I turn red very easly. Iv had flushing problems before I took adderall and I always thought I was just a shy person. I'm nervous how I will feel when I fly to Florida in a couple of weeks, when should I stop taking it before I leave? Thanks!
