Is 350mg of diphenhydrome too much?

Hi, i can't help but be extremely concerned about your future if you carry on this way. I'm not lecturing, i have been in a similar position in the past. Believe me, i know how horrendous it is not to be able to sleep, but you need to find another way. The damage you could be doing to your vital organs could be really serious. You mustn't just stop taking the Diphenhydramine as you will likely suffer very bad withdrawal symptoms. I don't know what your relationship is like with your doctor? Could you ask for his/her help in weaning you off this medication? Or is there another service you can use? I've added a link to show you what can happen when you overdose on Diphenhydramine, not to scare you but to inform you, and show you what signs to look out for which may mean you need to get to hospital

Its about 7 times too much. You need to get yourself off of it now. Start by cutting it back every few days decrease another pill. I know you are saying but I won't sleep. Believe me, what you're doing isn't sleeping, its putting yourself into a coma every night and you're not getting a nights sleep.
