They have little effect on the muscle tension because it's not the same thing they target -- it's a conscious (well, sort of) movement of your muscles. Unless they paralyzed you, they wouldn't really help :)Also, I suggest tylenol for headaches instead of ibuprofen. Ibuprofen works well for body aches and pains, but I've found it to be a very poor "pain reliever." It's a very nice anti-inflammatory though. Tylenol is the opposite. Aspirin is a nice both, but not as effective for either I find. Also, don't combine aspirin and ibuprofen. It's bad. Brain bleeds and stuff can pop up, especially with the increased blood pressure from stimulants.You're describing migraine headaches, I think, though (I don't get that almost ever, personally -- my headaches are different places). Those are notoriously difficult to treat with pain meds. By the way, you do develop a tolerance to these things (just like meth), you know. So bear that in mind. The tolerance doesn't protect your organs as they filter it out of your blood though, unfortunately, so upping the dose to make them work carries with it that added risk.
