Once in a while I will take phenibut, about 1.5g on Sundays. I usually take it anywhere between noon and 3pm. I have taken a half tab or about 12.5mg of doxylamine for sleep on the same days. The next day I feel terrible and grogginess lasts all day. When I take doxylamine alone I feel good within in 60 minutes of waking up. My question is do these two interact negatively and has anyone else ever experienced this before? Last week I took this combo and it was one of the worst feelings ever, like I just could not wake up all day on Monday.
