I took 2 50mg Nytol's (Diphenhydramine) after using Alprazolam over the weekend. SWIM only needs very low doses of dip to get a good effect. As the thread titles suggest sex then took place a good hour to hour and a half later, and at 'the moment' I could only describe the feeling as startling. SWIM's face, head and neck area felt the most intense buzzing / numbness as did other 'places'. The feeling was so strong I couldn't enjoy it after a few seconds as they got scared that as the feeling was so intense, something was 'not right' and if it got stronger I would pass out, or worse. Which kind of half ruined what was an amazing experience. Doubtful I know, but just wondered if any you's are bold enough to confirm similar effects or what caused it - and is it safe?!
