Hello,
I am writing to you as my boyfriend and I went out on Saturday night (31st) December to celebrate New Years and we both were drinking alcohol and he drank quite an excessive amount, however, he said he has drank that amount before. So yesterday, he was feeling very sick, (tried vomiting but couldn't bring anything up, couldn't stomach any food until about 7pm last night when he ate half a sandwich which seem like hangover related symptoms, however he is experiencing extremely high temperatures, even today (2nd January) and I am very concerned what this could mean. He says he is very cold but to touch him he is very very hot. Do you think he could have had his drink spiked on Saturday night while consuming alcohol? Or does this sound like anything else you are familiar with?

Thank you for your time and I very much hope to hear back from you ASAP as I am very concerned.
I appreciate your efforts

Warm regards,
Ellie
