<s>[INST] I have had severe allergic reactions several times that have sent me to the hospital.  These have happened over the course of 10 years.  They happen only at night after I have been asleep for at least an hour but sometimes after I have slept a few hours.  They are becoming more frequent.   Any weird allergies that only make you sick at night?  It starts with an upset stomach and then moves to either my insides becoming hot or my hands and feet itching.  Sometimes I can take a benedryl and be fine but sometimes I go into anaphalactic reactions.  I had an epipen for six years and never had to use it and know have had to use it twice in 3 weeks. [/INST] Hello My Friend!!you need to get an allergist option and advice on your exposure to allergies .he will order for a Sr. IgE. AEC, & PROCEED FOR (AST)ALLERGEN SKIN TESTING.you at the earliest undergo AST.in General IT IS SEEN THAT A PERSON WHO HAS THIS ANAPHYLAXIS IS LIKELY TO GET MORE NO OF ATTACKS SO BE WATCHFUL AND SPEED UP YOUR ALLERGY ORIENTED TREATMENT.EpiPen surely saves but using that frequently is not a good answer to your current problem so seek and advice from allergist to get advice from how to lead an allergy free & EpiPen free like. </s>
