As doodle_333 says, making yourself sick is not normal, and it is not ok. I know you have said you know the risk factors, but please, please do be careful of the risk to your heart, your teeth, your oesophagus, your stomach. The feeling of bloating is awful, but in the long term this will make it worse (especially if you do eat little during the day, because your stomach will not be able to cope with regular amounts of food so well).
The DSM-5 criteria has actually reduced the frequency of binge eating/purging to at least once per week (rather than twice weekly) now, although you don't mention if you binge eat. Even if you don't meet the criteria for bulimia nervosa, as said it is also possible that you could be classified as EDNOS (eating disorder not-otherwise-specified) (or Other Specified Feeding and Eating Disorders and Unspecified Feeding and Eating Disorders, as it has now been renamed). E.g. there is also now ' Purging Disorder', which is classed as "recurrent purging behavior to influence weight or shape (e.g., self-induced vomiting, misuse of laxatives, diuretics, or other medications) in the absence of binge eating".
Either way, please, please do be careful. Purging is not as effective as it seems, and it is really, really not worth it. Please do try to speak to your GP (or another GP) again about this.
