I'm Immune to Caffeine

[sthief09]

what do I do? after getting 5 shots of espresso on ice twice a day for the last 3 months, it doesn't work for me anymore. I think bumping it to 8 shots would probably be really bad for me, but I'm chronically tired despite going to bed more or less at hte same time every night and getting 7-9 hours. I need something to pick me up. red bull also doesn't work for me.

and speed and coke aren't an option
